Headlight issues any clues anyone

[Terminator]

My parking lights work, my high beam works I have anew light switch and presumably headlights worked when I got the RWC but neither work now.

Fuses are fine.

Assuming I haven't blown 2 globes simultaneously where else should I look?

Sounds like the headlight switch? Trace it back with a test light ...

Bugger it's a new one!!!

not that rare that 1 bulb blows and then another follows due to change in loads etc, check for pwr at bulb holder before replacing switches
