Turn Signal Socket Code

[AugustDiesel]

I have this question posted in my build thread but figured it may be more appropriate in this section, since it is gmt-400 related.

Can anyone tell me what the 4 digit code is that identifies the socket style of the parking lights and side marker lights on a 93 GMT-400? Trying to nail down parts for my father-in-law’s truck. We are replacing the housings for the headlights, park lights, and side markers, as well as, replacing with all LED bulbs, just want to make sure we purchase the right parts the first time.



Thanks in advance.

Andy.

Was able to find the information elsewhere. Sharing here in case anyone finds it helpful:


Low Beam headlight 9006
High Beam Headlight 9005
Front Side Marker 194
Parking Light 2357

If incorrect, feel free to post up.

I know this post is old. Those are bulb type numbers. Iirc the park lamp should be Amber and have NA sufix
