Lifetime Members 7,935 Member For: 21y 5m 6d Gender: Male Location: Sydney Posted 04/03/06 10:10 AM Share Posted 04/03/06 10:10 AM Ok,Some of you may have read my thread about how I have replaced the tail lights and reverse lights with LED's. While they look awsome, they WILL cause problems with your BA/BF.The 2 main problems caused by LED's are Cruise control will not work and also Traction Control will not work. The CC will power on, but will not set the speed, while the TC will just not work at all with the light permenantly on when you drive.I removed the LEd's and put the standard globes back in today and both my CC and TC are now working properly.I thought it was worth starting another thread to let you all know about this before you go out and try this mod Link to comment https://www.fordxr6turbo.com/forum/topic/23816-do-not-used-leds-in-the-tail-lights/ Share on other sites More sharing options...

Looked at the circuit for the brake lights... then put it on the too hard basket...What would be cool is the brake force indication, like the BMW's have the harder you press the brake pedal the more LED's in the brake lights light up.

LED indicators do not have have over-voltage protection circitry so care has to be taken when used with other electrical devices (ie solenoids)it also stats that they have a lower current draw than a normal incadesecent globe. i think this may be the problem...you could do a current draw test on the regular bulb and the LED and then fit a resistor to ensure the LED draws the same current as the incandescent globe. i'd talk to an auto sparky as well to see if you need to run a diode to prevent any current leakage so you brakes light arent on and glowing dimmly when driving or so that your cruise control doesnt get a constant cancel signal from the brakes (im no expert this is just a half informed guess.... ) Edited 04/03/06 10:39 PM by hiddeous Link to comment https://www.fordxr6turbo.com/forum/topic/23816-do-not-used-leds-in-the-tail-lights/#findComment-356203 Share on other sites More sharing options...

cqae Member 229 Member For: 21y 8m 14d Posted 05/03/06 04:51 AM Share Posted 05/03/06 04:51 AM current draw is the cause-well sorta. basically the cruise "see's" earth through the globes, when they are activated via stop light switch it no longer sees earth due to the 12v sent down that line. This is in confilct with popular belief that the system is looking for the 12v that is sent from stop light switch. I tried them in my ute about 18 monthes ago and struck same problem. A plus with the led globes is the lack of current draw & therefore less load on items like switches & connections, but problem is they confuse somew electronics. the simplist way to solve would be some sort of load simulator which coujld be connected in parallel to the stop light circuit. I looked into it but could never be bothered, seemed that the effort required was more than replacing the odd globe.

Just tuck them away in the corners of the boot somewhere and they will give the CC and TC the correct current signal while allowing you to have the "nicer" looking LEDs in your tail-lights and brake lights. You can of course do the same with your indicators but I don't think there is any issue with these on the BA/BFs.
