Title: Quick & Simple, What light bulbs do I get?
Post by: treepete on January 17, 2009, 09:31:17 pm
Sorry to ask this, but I'm a new owner and I just need quick help. For me, it's easier to ask this than try to look it up.

I have found a light socket under the dash area by the ashtray. there is not a bulb in it right now. I read on this forum that It can be replaced withe the 1056 or 1057, can anyone verify which it is for me, please? I would like to have that acting with the dome light for creature comfort when entering/exiting the vehicle.

Also while I have your attention, the front turn signal bulbs ( behind-the-grill-style) are they 2057a or 1057a?

the PO just let the trucks parts break and not get replaced. they were removed as well.. its weird. I found the signals not working,... then I went to check the bulbs, AND THEYRE GONE.   

thats why im asking. sorry to bother you with this lame newb question.

Pete

the only difference in the 1057 and 1056 is the brightness of the bulb i think the 56 is brighter but not sure and your other bulb should be a 2057a since its both a turn signal and running light bulb, the bulb has 2057 having 2 and 1057 only having one

Your underdash light should be an 1156. At least that's what mine is.

1157, 2 element-tail light/brake light
1156, single element, reverse light
1157a, same as above but amber in color meant for front turn signals that are clear.

I think the 2057 series is the newer style for the 88 on up CK but not positive on that without going in the cold garage and finding one.
