As above..the light doesn't flash, it will stay on constant but only if I wiggle the H/L lever into a certain position. Im guessing it is something to do with the two switches(black/grey??) above the transfer case but they're a bugger to get to...any thoughts on how to adjust or what you think may be the prob? As ever thanks for all the help. You guys have really kept the truck going! Nik Trust your all safe

I don't think there's an adjustment on the switch - it's probably just a knacked switch.

Cheers H...easy or fiddly to replace?

Might just want removing and a good contact clean. It obviously works but just slightly loose. Can they screw in a bit more like the reverse light switches. I can’t remember
