I've noticed a little problem with my rexy, sometime when i switch the light from low to high by pushing it towards the dash, my lights will just turn off, but if i pull on it for the momentary high, that always works, when i try to trouble shoot the problem at home, they just work everytime when its sitting, so its gotta be something to do with when i'm driving, i can' find any patterns for them of when they work and don't

 

Maybe the reason it only happens when driving is due to the heavier load on the electrical systems. The contacts get a little buildup on them, then it is harder to actually make the connection needed when you don't have an abundance of juice for it.

Check this out, maybe it will help...

I have done this on two cars which had this problem fixed them both

 

did the trick for me too. my high beams didn't work at all before I cleaned the switch, now they work most of the time but have the problem you described now and then. I let my switch sit overnight with the cleaner on the contacts.
