Default 3rd Taillight? ('86 Coupe)

When I bought the car there were no bulbs in the assembly. I think I have the correct bulbs (#891)... but they don't seem to fit in the lightbar. What I am wondering, is whether there are seperate holders/sockets for those bulbs that I am missing? Any ideas would help, I know there have been tons of posts on the 3rd light but none are taking on this.
Any pictures would probably really help. TIA

891 is correct, they should slide right in to the assembly and then theres a little click :confused:

I hate mine- the dang bulbs just burn out anyway; I'm going to look at replacing with small LED lights- for what these bulbs cost, I figure it should pay off fairly quickly!

The third stoplight has a rectangular circuit board in it with 4 places that you can plug the 891 lamps directly into. The 891 lamp is a bi-pin lamp and the circuit board has 2 spring contacts in each lamp position. If you will look at the circuit board you will see 4 paired holes to accept the bi-pin lamp.

Hi, I replaced mine with High intensity LEDs. It cost me about $20 total to make it.

:cool: Looks good!!! I bet it gets attention better too. There's a guy in town here that put LEDs in the "bow tie" on his grill on a SS Impala. A how-to would be nice!

Truly, one of the more clever projects I've seen on here, Brookman- would you enlighten us- are the LED's and circuit board readily available? What LED's did you use? Thank you in advance for shedding any light on this (pun intended)- john

LEDs http://sales.goldmine-elec.com/prodinfo.asp?prodid=3853
Caps http://sales.goldmine-elec.com/prodinfo.asp?prodid=5788
if you know how to etch circuit boards http://sales.goldmine-elec.com/prodinfo.asp?prodid=6552
I used the kind of curcuit board with all the pre drilled and copper pads. I had to join two togethter to get it long enough. You can buy that type at Radio Shack.

Thanks! A very worthwhile project for anyone who has bought too many of those overpriced bulbs!

Well I've got some good good news!!!
Ok, so finally after I am looking at the pictures (thanks Brookman) I decided to do soem backtracking. Well the light bulbs I got from a friend who swore they were #891's, well I called him the other night and he tells me where he got them from (it cost me 8bulbs for 3$ btw) ....from a 3rd stoplight on an '86 firebird. Anyway to make a long story short I did some checking they were actually #906's :bb (ME=DUMB) but I did some tweaking to them, and I am in the money!!!!!! So yeah, we'll see how they hold etc... but it'll do until I feel like spending 60$ lights. Anyway thanks for all the help!
:steering:

[EDIT for correct bulb #906

Not me- I am sick of these bulbs burning out, and the LED's should solve that little headache, plus they just look cool- in addition, there is a noticible difference in how quickly LED's light up, if you've watched any LED taillights, it's very impressive- this is a very worthwhile modification, working on mine tomorrow, thanks again Brookman.
