2003 bmw gs1150r abs servo

[Timmy1honda]

Hi I've a 2003 gs1150 non adv and have just fitted a led rear light unit stop tail , got it new from motorworks , works fine but I've now a red warning light on dash showing, does anyone know how or if this can be turned off? I presume the bike thinks I've a bulb out

You may need a load resister to tell the bulb failure circuit you have a working bulb, unfortunately this will mean it wont indicate a bulb failure in the future.
The resistor should be in parallel with the brake LED and will be around 6 ohms and have a rating about 50watts
It is best to use a finned metal resistor to help dissipate heat, something like this http://www.ebay.co.uk/itm/LED-Indic...arts_Vehicles_CarParts_SM&hash=item4832a07f6d

I would contact Motorworks if I was you. There are two versions of these led units in circulation. One for non abs and one for the IBS system, which your bike is.

Though the Motorworks write up says it is suitable for both types, clearly it isn't. If it doesn't have the gold coloured resistor fitted, then in all likelyhood it's the wrong type.

Correct about the resistor, but it wouldn't mean he'll not get a bulb failure warning if a different bulb blew

The resistor just sets the level of apparent power consumption and resistance on the circuit back to what it would be if it was a normal bulb rather than an LED in there.....therefore, another bulb going would return it to 'fail' conditions and it will indicate again

The one he will be modifying is the brake light bulb, it will cease to function with a load resistor in circuit. Brake bulb failure would not be indicated. Agreed other bulb failure will not be affected.

All very well in theory, but in practice it's only the stop/tail bulb that the 1150 monitors?

Which means that the tail light may also require a resistor to prevent false failure light, This mens the bulb failure is all useless as it wont detect stop or tail light failure, but at least it will test the brake light switches.

I'd guess that aftermarket led bulbs designed for the servo ABS would have suitable resistors to mimic both standard filaments? I don't think leds are all that prone to failing open-circuit (they don't blow like conventional bulbs) so the now-useless bulb failure detection is also largely irrelevant?
