LED Tail Lights

Gary, check the earth on the lights. Poor earthing can play strange tricks with the lights such as all lights blink with the flashers, stop & tail come on together when braking etc. Probably nothing wrong with the LED lamp assemblies just a poor earth.

I am no expert but for flashers, sometimes the resitance of the led's is too low for the system to work properly. Adding resistance helps.

Is ths one side or both sides?

Make a difference to the answer.

Both sides - however by placing a test lamp (bulb) across 1 side it fixes both sides if that makes any difference. We found the problem after installing a cruise control. When you touch the brakes the control turns off ie goes into neutral. It all worked fine until during a shower of rain I turned on the lights and the control "dropped out". Had the control checked and thats when they found - by turning on the lights the brake light came on - so the cruise stops. Weird!

Okay, I'll bite, but here's the thing... I'm NOT an auto electrician, or electrician full stop.

Digital electronics has some major differences than analogue, and it is sometimes a pain to get them to co-operate.

Now, I'm guessing, that with the advent of having your cruise control fitted, there is now a SMALL inherent current turned ON at all times, to sense if the brake pedal has been depressed.

Now, old logic would suggest that if the brake pedal was depressed, then the current would go from OFF to ON, therefore knocking out the cruise control. Digital logic would suggest, that you have a SMALL residual current ON at all times, waiting to be turned OFF by application of the brake pedal, which is by far a much SAFER way of monitoring.... no current....turn the system off.

So, this small monitoring current, which would simply be diverted when the brake pedal is depressed, by way of path of least resistance, is possibly the culprit, because traditionally, LED's only require a few volts to work, and are subject to voltage drops.

As I said, I'm just shooting in the dark here, but it fits with your explanation.

I'm not an auto electrician but the young bloke put LED lights on the tonka truck tray he built for the Hilux.He soldered in a festoon bulb before each led light(hidden in tray frame). apparently this provides the necessary resistance.
all I know is the lights work ok
cheers
