No power driving lamps

[SwankBaton]

I've got no power to low beams (3R) - all fuses in footwell are fine.
Any ideas where next to look?

Side lights and main beam are fine, as are numberplate bulbs etc.

Cheers

If they're both out, the first thing I'd check is the relay.

I had same problem it turned out to be a badly corroded bulb holder in the rear light cluster. New one from a breakers and some sealant and it has been fine since.

It was / is the relay.

Tried an off the shelf item from Halfrauds but its not right (one light always on).

Anyone got a source for the correct relay?

There are two common types of 5-pin relays used in the Noble. One is a double-throw, which switches between the two output pins, turning one off and the other on, and vice versa. The other is a single-throw, which turns both output pins on and off simultaneously. If you look at the pin labeling, the double-throw has a pin 87, and a pin 87a. The single-throw has two pins marked 87. My guess is that you got a double-throw, but what's needed is a single-throw. Over here in the States, usually a store that carries one type of relay carries both - you just need to specify which one you need.
