Just a quick question. I have fitted one of the Wipac led indicator sets, to my defender which included the adjustable wipac relay. Will this change have any effect on the towing electrics????

Thanks Dave

The wipac flasher relay is pants, and is troublesome with trailer hook ups. WIPAC Relay all you can do is adjust the flash rate, it puts the trailer light on dash when you are not even pulling a trailer, plus it burns out real easy.
( ask me how I know this !)

Use the RDX one, it works with LED and normal bulbs and any combination of the two, it also has manual trim, this os not for flash rate for for activation threshold depending on bulbs you have including trailer ( turny knob thingy!)
So you can set it just right for the trailer hook up!
have a look on that auction site
