Have changed the 4 clearance lights and 2 front marker lights to led. But when i turn lights on they blink when the indicators come on.the caravan (coromal) has upto 5 wires in one light minimum 3.
Should i have chain hooked up or on ground to earth, and what is making the lights blink as i havent (knowingly) touched the indicator wires.As they say a little bit of knowledge is dangerousd

Well have taken van to friend a auto electrician. He tells me it is a big problem when you mix Bulb lights with LED reckons big job to find the bad earth as leds use so little current that the bulb lights will chase the led current. He is going to install the leds which i had installed then removed. Tow vehicle is Pajero 3.2 Diesel/gas. thank you for assistance hope we all learnt something, he is not going to pursue bad earth

Hi Harry.

Don't want to contradict your auto electrician friend - but there is no problem at all in mixing LED globes with conventional globes in a circuit - provided that all the wiring and connections are correct and sound. Have done it many times on all sorts of vehicles and trailers without problem.

I agree with the earlier post that you have a bad earth problem. If this is the case, this needs to be traced and repaired, otherwise you will continue to experience problems no matter what lights you have installed.

Having said that, if you can convert ALL the globes on your trailer to LED, you will be better off.

Cheers .......... BM

"He tells me it is a big problem when you mix Bulb lights with LED reckons big job to find the bad earth "
- and he claims to be an Auto Electrician !!!!!!!

Pajeros have no Bulb test Pulses and will not have any problems connecting LED bulbs - I've replaced Tail and Brake light bulbs with LEDs with absolutely no side-effects.

While bulb test pulse systems can be good, thay can also be a pain in the butt at times. I had a bullbar fitted to Disco a while back, and because it has another set of park / indicator lights (with bulbs), the trailer test light on the dash now flashes with the indicators all the time. Looking around at the moment for a set of LED park / indicators to replace the ones in the bullbar, as this is the easiest way to fix the problem (reduces the total resistance of the circuit).

On the flip side, both my trailers (garden and camper) now have LED lights only. The camper is OK as there are enough LED's with clearance lights etc to provide enough resistance that the Disco's circuit can "sense" that they are working. The garden trailer however, only has a set of LED tail lights - not enough resistance here, and the Disco will not sense these.

I've fitted the Disco and both trailers with the new LED indicator trailer plugs. These are brilliant. At least if you do have a problem, these will give you a pretty good idea where to start looking.
