I will be wiring up 2 Rally 4000's to my lux tomorrow,
Is there an advantage of using two relays as one per each light as i have seen it on some 4x4's, or should i just use one relay per 2 lights.

Ive had quite a few relays go bung so based on that I reckon 2 relays twice the trouble

Thanks for that Davoe,
I may have a spare relay sitting in the glove box then for a just in case.

I'd agree with Davoe.
Use a single relay, but one with 2 pins... 1 for each light.

I have always used two relays.
It's not a simple matter of the relay contacts being able to handle the current or not, if they handle less current, they will last longer. PLUS when (not if!) the contacts finally fail, you will still have one light to get you home!
You should carry some spare relays as well..

It's easy enough to bypass a dud relay to keep your lights working so using 1 or 2 is just a matter of choice.

Over many years I recommend two relays, not the two in one types though. Single Hella ones never failed me. Also use two fuse holders, the black ones or thermal circuit breakers, as fuses can overheat and melt.
