Hello all just curious if any others have run into this. This a.m I decided to change the bulbs in my 2002 dmax. I bought the sylvannia 9005/9006 series bulbs down @ autozone. I loaded the connecters with diaelectric grease and tested them. Day time running lamps no longer work. Now I have to use the headlight switch to make the hi and low beams to come on at all. While the truck is running the lights are 
off and if I hit the dimmer switch the high beam indicator on the dash lights up but no headlights unless I run the switch? I put the stock bulbs back in & everything works fine.
