FIELD OF THE INVENTION
This invention proposes a newly designed turn signal indicator that is visible from the front, side and back sides of two-wheeled vehicles.
BACKGROUND
Most of the motorcycle accidents happen during the lane changes/turnings because the vehicle coming from behind is unaware of the motorcyclist's intention to change lanes/turn. Currently, the vehicles coming from opposite direction is informed using the front facing turn signal indicators and the vehicles completely behind the motorcycle is informed using the rear facing turn signal indicators.
If a vehicle is very close behind and beside the motorcycle, then the vehicle driver will not notice either the rear facing indicators or the front facing indicators. Unfortunately, these are the vehicles which pose the biggest danger in case of a lane change/turning.
Hence, instead of using the front side indicators to signal only the vehicles from opposite side, a modification idea is proposed so that the indication will also be visible to the vehicles close behind and beside the motorcycle.
DISCUSSION OF THE PRIOR ART
US 3430229 A titled “Unitary signal device having front and side signal areas” discloses a unitary signal lamp employed in automotive vehicles and the like incorporating lighted turning signal means that can be visible from both front and rear, a side marker signal light and a side reflector signal. All of these signal means are conveniently incorporated in a compact unitary assembly.
US 5101326 A titled “Lamp assembly for motor vehicle” discloses a lamp for a motorcycle, such as a side marker or clearance lamp that uses light-emitting diodes (LEDs) instead of incandescent bulbs. The lamp includes a housing which precisely positions the LEDs to provide a desired light pattern. The housing comprises a pair of fixture halves that are positioned in facing abutment to form a

fixture for positioning and holding the light-emitting diodes in place. Each half of the fixture includes LED positioning grooves which cooperate when the fixture halves are assembled to accurately position and hold the LEDs in desired positions. A transparent lens is placed over the housing.
US3275816 titled “Lamp assembly for motor vehicles” discloses an automotive vehicle signal lamp with double lenses arranged back to back with a side reflector which divides lamp housing into two compartments. A single baffle element operates as sealing gaskets and light reflectors for the two lenses. The signal lamp provides direction signal indications both forwardly and rearwardly for a motor cycle.
SUMMARY OF THE INVENTION
This invention enables a motorcyclist to signal the vehicles behind and besides, about the intention to change lanes or turn to a side road. Thus, reduces accidents caused due to non-visibility of turn signal indication and hence improves ride safety. The design also enables the motorcyclist to notice the turn signal indication blinking and hence reducing the chances of riding unaware of the indicator being turned on. The forward facing indicator consists of a light source, a reflector for channeling the light, an opaque housing that holds the reflector and the light source in place, and a transparent cover through which the light goes out as in any turn signal indicator.
The present invention proposes a turn signal lamp design in which the indicator housing and the reflector are designed in such a way that the light of the forward facing turn signal indicator is visible on all the sides, front, side, and rear of the motorcycle. The design also comprises re-orienting the lighting source which is a bulb/LED at a particular angle with respect to the longitudinal plane of the motorcycle in order to ensure a distributed spread of the light to the front, side, and rear portions. A part of the indicator rear surface that faces the rider is covered by the opaque material, while the other part which is visible to the

vehicles behind is made transparent. This partial opacity on the rear side will ensure that the motorcyclist notices, enough light to be aware that the indication is turned on and at the same time is not disturbed by the blinking of the light. The idea also covers the use of light guides to channel the light to the rear side either from a separate light source or from the primary source itself.
The invention can be applied directly to motorcycles and mopeds having their turn signal indicators projected out of the vehicle body and extended to include two opposite facing light sources, within the same housing using separate reflectors for front and rear side. The design can be applied to any form of two-wheeler having the rear part of the forward facing indicator visible to vehicles coming from behind.
The present invention is turn signal indicators of a two-wheeled vehicle to reduce accidents during lane changes and turning side road comprising, a connector, a reflector, an opaque housing, a transparent cover, a light source, a reverted light source, and a light guide. The connector aids to attach the turn signal indicator to the vehicle. The opaque housing holds the reflector, the light source, the reverted light source, and the light guide in place. The reflector is obliquely inclined with respect to an axis Y-Y’ which is parallel to the vehicle longitudinal axis X-X,’ and the transparent cover covers an area formed within 270 degrees surrounding said light source. The channelling of light is by the reflector. The channelling of light is by the light guide. The indicator housing and the reflector are designed such that the light of a forward facing turn signal indicator is visible on all the sides, front, side, and rear of the vehicle. The lighting source is oriented at an with respect to a longitudinal plane of the vehicle for a distributed spread of the light to the front, side and rear portions of the vehicle. The reverted light source along with light guide oriented at an angle with respect to the reflector illuminates the lower portion of the indicator including the rear portion. A part of indicator rear surface on rider’s side is covered by the opaque housing and the part visible to vehicles behind is transparent. The partial opacity on the rear side ensures that the

rider notices the light and be aware that the indicator is turned on without being disturbed by the blinking of the light.
In this invention, the double side indicators are employed on both LH side and RH side of the front end of the vehicle for better safety. The same design can be applied to include two opposite facing light sources within the same housing using separate reflectors for front and rear side and also to any form of the two-wheeled vehicle having the rear part of the forward facing indicator visible to vehicles at the backside.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS
Figure 1 shows the conventional indicator on the front end of motorcycles (RH side). A turn signal indicator of motorcycles consists mainly of four parts, a light source, a reflector for channelling the light, an opaque housing for holding the reflector and the light source in place and, a transparent cover, through which the light spreads out. Typically, in motorcycles, there will be four turn signal indicators, a pair on the front end of the vehicle facing forward and another pair on the rear end of the vehicle facing rearward. A vehicle, close behind and beside the motorcycle can neither see the backward facing indicator, nor the forward facing indicator.

In four wheelers to have an extra indicator is a legal requirement, which is side mounted to intimate the vehicles which are passing adjacent behind and besides the four wheelers. There is no such mechanism present in the two-wheelers since it is not a legal requirement. The danger posed by the lack of such arrangement affects the two-wheelers too.
Figure 2 shows the proposed turn signal indicators for the front end of motorcycles (RH side). The idea is to introduce modifications on the forward facing indicator such that the vehicles close behind and beside the motorcycle can also see the lane change / turn signal.
Figure 3 shows the cross-sectional view of the proposed inside of the lamp along with the lightning zone. The forward facing indicator consists of a light source 5, a reflector 2 for channelling the light, an opaque housing 3 that holds the reflector 2 and the light source 5 in place, and a transparent cover 4 through which the light goes out. The entire housing is attached to the vehicle by a connector 1. The idea is to re-design the indicator housing and the reflector 2 in such a way that the light of the forward facing turn signal indicator is visible on all the sides, front 8a, side 9, and rear 8b of the motorcycle. To achieve the above, the reflector 2 is obliquely inclined with respect to an axis Y-Y’ parallel to the vehicle longitudinal axis, X-X’ and the transparent cover 4 covers an area formed within 270 degrees surrounding said light source 5. The idea also covers the use of light guides to channel the light to the rear side either from a separate light source or from the primary source itself, as shown in Figure 4. The design also comprises re¬orienting the lighting source 5 which is a bulb/LED at a particular angle with respect to the longitudinal plane of the motorcycle in order to ensure a distributed spread of the light to the front 8a, side 9 and rear 8b portions. A part of the indicator rear surface which faces the rider is covered by the opaque material 3, while the other part which is visible to the vehicles behind is made transparent. This partial opacity on the rear side will ensure that the motorcyclist notices, enough light to be aware that the indication is turned on and at the same time is not disturbed by the blinking of the light.

Figure 4 in which the turn signal indicator consists of a light zone which is partially divided into two parts by the reflector 2. The light zone includes a light source 5 which is primary and mounted perpendicular to the connector 1, above the reflector 2 to illuminate the upper portion of the indicator. A reverted light source 6 is included in the reflector 2 and a light guide 7 directs the light beam towards the lower portion of the indicator and to the rear portion of the indicator which is next to the opaque cover 3. The opaque housing 3 holds the reflector 2, the light source 5 and the reverted light source 6 in place. The rider facing part of the rear surface of the indicator is covered with the opaque cover 3. The rear surface of the indicator, excluding the opaque cover has the reverted light source 6, the reflector 2 and the primary light source 5 which is visible to the vehicles behind. The partial opacity on the rear side ensures the rider is aware that the indication is turned on without any disturbance due to blinking of the light.
Figure 5 shows the application of the present invention in a driving scenario. The driver of a two-wheeler is about to do a lane change 10 and has two options, either to either take the lane on left side 12b or to take the one on right side 12a. The driver of the two-wheeler has to indicate the vehicles which are coming from behind 11a, 11b about his decision. In this case, the vehicles from behind could not view the front indicator or the rear indicator. The double sided indicators on both LH side and RH side of the front end of the two-wheeler help the driver of the two-wheeler for a safe lane change by informing the decision to the adjacent vehicles.
The present invention can also be extended to include two opposite facing light sources within the same housing using separate reflectors for front and rear side. The same design applies to any form of two-wheeler having the rear part of the forward facing indicator visible to vehicles coming from behind.
