2007 ls no rear running lights

2007 ls 72k, Rear turn signal bulb went out i couldn't find the recommended 3057kx after 3 packs of 3057's i went to the dealer and bought their 3057 and still no running lights.The brake, turn signal and reverse lights are fine.Prk lamp fuse is good power to it is 12v if i remove it w/running lights on the fronts go out. My girl hit a deer on halloween 2008 front drivers side light assembly fender were replaced maby there was some hidden dammage? No power to the rear sockets with the running lights on :screwy: so im thinking its going back to the colision shop its under warranty there..:banghead:

So all 4 lamps do work, but power drops out to all 4 sockets when headlamps are activated by the stalk or automatically? Odd one fo-sho. :confused:

no , there is no running lights in the rear at all. All the other lights are fine

on the 4 wire scoket i only get power to the brown wire its 0.8v with the headlights on. :(

Check all of the contacts to ground and see what the Ohms values are with a digital VOM. Sounds like the bulbs are acting like the circuit protection rather than the fuses.
