Yamaha YZF R15 custom LED Tail Lamps

Check out the new LED Indicator here

A known fact is that a stock R15 comes with an incandescent tail lamp, with a power rating of 5w/21w. My friend, who  owns a R15, got bored with the regular power consuming tail lamp and wanted to get a make-over, using highly efficient and better looking...LEDs. Then we sprung into action immediately and decided to get the job done.

COMPONENTS USED:

1) PCB
2) Red-LEDs (46pcs)
3) Connecting wires
4) Nuts, Bolts , Washers
5) L - joint
6) Resistors (390 ohms ->10pcs, 510 ohms ->2pcs)
7) Diodes (IN4007 -> 2pcs)
8) Bulb connector


PROCEDURE TO OPEN TAIL LAMP SECTION:

1) Remove the seat

2) Remove the grab - rails, by opening four 12mm bolts

3) After removing the grab-rails, open the two 10mm bolts on the tail cover

4) After removing the 10mm bolts, slide out the tail cover carefully.( It is held by a slide mechanism, so you must be careful)

5) Gently unscrew the plastic cover and remove it.

6) Remove the Red cover from the lamp assembly

The picture below, shows the view of the completely opened tail lamp section

THE PLAN:

1) Tail lamp

2) Brake lamp

MAKING THE LED SETUP:

1) We took the internal measurements, cut and filed the PCB to the proper shape, so as to fit in the assembly comfortably.

 
2) We drilled two holes on each PCB for fitting the L- bend and for the screws to holds the assembly firmly.

3) Circuit diagram (LED)

4) Circuit diagram (Bike's output to LED setup converter)

5) The LEDs and Resistors are soldered onto the PCBs according to the circuit diagram.

6) The L- bend is fixed, hence joining both the PCBs in a calculated angle. A bulb connector is soldered with the wires.

7) The connector is placed into the bulb socket and the entire tail lamp section is fixed back.

RESULT:

After a lot of hard work, dedication and patience......

COST: Rs.100(approx)

TAIL LAMP OUTPUT: 1W (STOCK 5W)

BRAKE LAMP OUTPUT: 2W (STOCK 21W)

The entire LED setup is plug n play i.e. it can be removed and replaced by the stock bulb in just 5 minutes. Does not void WARRANTY of the bike.


NOTE: No changes were made in the bike's wiring.


ENJOY THE RIDE!!!
