signal light part #

[aquaman0001]

Hello,
I am getting a fast cadence on my right turn signal like there is a bulb out but all bulbs are functioning. The right side front turn signal fixture has a lot of corrosion in the wells were the bulbs fit. I am thinking about replacing this fixture. I took it out but could not find a part number. Anyone familiar with this fixture? Any help would be appreciated.

I am assuming that you have the LT which has the composite headlamps. The part # for the park lamp socket should be 12003759 or AC-Delco #LS7.

For people with the Single headlamp the part # for the park lamp socket should be 12003757 or AC-Delco #LS6.

I checked with Gmpartsdirect and they show as valid numbers.
