LED Rear light - LAMPR - The fix !!!!

--------------------------------------------------------------------------------

For those following my recent thread on the fitting of my LED REar Light here is the fix:

You will recall the need to fix Resistors, to trick the bike electronics to think a bulb was connected rather than LED's thus avoid the LAMPR warning. This is due to the LED consuming less power thus the bike thinking that a bulb had failed.

After much Email discussion with SMB (My thanks to him) He suggested a value for the resistors.

I ordered these from Ebay, and settled for Aloy clad, for ease of mounting and better heat sinking.

The Brake light is 10 Ohm and 25 Watt.

The rear light is way over engineered with a 39 Ohm 50 Watt. The 50 Watt is the overengineered bit.

This big resistor on the rear light and hardly gets warm when the lights are on. The brake light does get warmer. I mounted both of these on the metal plate, which the bottom screw attaches to, to mount the plastic rear panel.

The resitors get air but cannot be seen from the exterior.

All works OK and no LAMPR warning..:thumb

Again my thanks to SMB :beerjug:
 
Glad it worked OK.

The 50W was my mistyping, should have been 5.0W Sorry!!!!
However over rating appears to be a good move, as it is on all the time and will run cooler.
