DIY LED Tail Light

I'd been thinking about LED tail lights for while but, I was not satisfied with the cost, performance, or reliability. SoI planned to make my own.

The original plan was to solder thrity or soLEDs and a dozen resistors to perf board to make the light. But, then... the guy a Lee's Electronics showed me these LED modules.



And a new much simpler plan was hatched. I'd use two moduals and make it plug and play.

First I used an 1157 lamp and soldered my wires (and other parts) to the contacts on the lamp base. Then I filled the lamp base with 5 minute epoxy to hold the wires.



Bent a piece of sheet metal and used the sticky backing of the modules to hold them on.



I put a blocking diode in the circuit, I'm not sure if I really needs it but, it can't hurt. The resistor limits thebrightness of the "Tail Light" , increasing its value will decrease brightness. Wire colours are for "old" KLRs.




Results:

Factory tail light:



Factory Brake Light:



LED Tail Light:



LED Brake Light:



It's hard to see in the pictures but the LED lights are a lot brighter than stock. Also, (in case you couldn't tell) the colour is different. The LEDs are a lot whiter than the incandesent lamps.

Overall, I very happy with the results and I'll confirm brightness and visability the next time I find a KLR.Current is about 0.2A for tail light and 0.5A for brake, roughly 1/3 of stock.

Price is $35 with taxes :tup:

Very neat, love those homemade mods. Can't read the diode#, but can read the license plate note:).

Nice job :tup:

I like how u soldered into the bulb base:clap:

I broke all the bits of glass out, soldered onto the existing wires that used to go the filiment and covered the splice with shrink-tube.

Nicely done.:tup:
Now I'll have to make sure I can't see your mirrors.

I don't have one so can't say. The one I have is one of the spinner type led's. i do have a 68 smd led bulb coming which should blind people within 1 meter. scroll down the link to read about eyes within 1 meter. http://cgi.ebay.ca/2x-68-LED-SMD-Red-Rear-Stop-Car-Bulb-21-5W-1157-bay15d_W0QQitemZ220578579781QQcmdZViewItemQQptZUK_CarsParts_Vehicles_CarParts_SM?hash=item335b820545
Interesting. Is it really as simple as that??? ...just swap out the old bulb and put in newthe tail/brake LED ? (and one spare!) Let us know how you get on. Do they have them in Walmart? ;)

Very nice.

Adding the diode and resister to reduce the light for run lightingcould be adding

a potential trouble spot, resister failure, and to a lesser degree diode failure.

The light intensitycan be achieved by using the 2 banks connected as a standard

2 element lamp, the second one lights when the brake is pressed.

My 2 cents worth.

Thanks for the writeup. I'm curious about how reliable this setup is, please report back :)

Also, thanks for the link to the ebay set.
