light switch

[wibilly]

i just got my truck togather [not finished but togather] all lights working excepy dome and cargo. took it for a ride last night and just before i pulled in my neighbors drive way a headlight flashed bright .then without the engine running i turned them on to see if was still working and the other blew the same way. all other lights still work fine so i figured the dimmer switch shorted no wires seem to have gotten hot or anything. so tonight i put a known to be working dimmer switch and tw new halagen bulbs in and nothing ,still no head lights. i'm gussing it's the switch, maybe caused by a shorting dimmer or maybe it was the switch in the first place. what do you guys think? anything else i should check first? when the lights blew it acualy busted the glass on the filiment in side them on them both.
