Bertimus Posted January 11, 2021 Share Posted January 11, 2021 So I need to replace a fog lamp bulb and the rear window brakelight bulb on my 88. I've been reading though post after post and there seems to be more confusion as to the correct bulbs. So I'm coming to you guys for help. I'm not looking to upgrade to brighter lights/LED (unless it's the only option), I really want to keep the bulbs factory correct, because I read that certain incorrect bulbs/wattage can melt parts/draw more power. What are the factory correct bulbs that I need? Thanks mates! Link to comment Share on other sites More sharing options...

This was exactly what I was looking for! You're a lifesaver @Ronnie. So my guess was right, convertibles and coups differ as far as the rear window brake light! That's really what I needed to know! I'll be needing a 1156 😎 Link to comment Share on other sites More sharing options...

Bertimus Posted January 11, 2021 Author Share Posted January 11, 2021 (edited) @Ronnie, I do have a quick question, my rear license plate lights are out (I think), but they are the ones directly adjacent (parallel) to the plate. On the chart you provided they are listed as 4- backup light bulb, and say they require 1156. But the lights perpendicular to the plate listed as 5, are not listed in the text. Does this mean they use the same bulb? If not which do they use? Also, since the lights listed as 4 are labeled "backup light bulb", does this mean they only turn on when in reverse? Thank you so much for your time Ronnie! 🙏🏽 Edited January 11, 2021 by Bertimus (see edit history) Link to comment Share on other sites More sharing options...
Ronnie Posted January 11, 2021 Share Posted January 11, 2021 That has been several years ago when I made that chart. To be honest I don't know why I left out bulb number 5. I guess it was just an oversight. If someone can tell me the bulb number I will add it to the chart. Yes, backup lights should only come on when in reverse. 1 Link to comment Share on other sites More sharing options...
Blue90 Posted January 12, 2021 Share Posted January 12, 2021 This is from page 287 of the Owner's Manual (not the FSM). Is this info wrong?🤔 Link to comment Share on other sites More sharing options...
padgett Posted January 12, 2021 Share Posted January 12, 2021 Know there is more than one trunk and maybe underhood light. Link to comment Share on other sites More sharing options...

Thanks for the info on the license bulb. I assume it is correct. I updated the chart on ROJ. Link to comment Share on other sites More sharing options...
padgett Posted January 12, 2021 Share Posted January 12, 2021 Seems like I have run into both single contact (1003) and dual contact (1004) bulbs in underhood/trunk lights on different cars (88 and 90 mostly). Just have to look at the socket. Only have 88 today. Link to comment Share on other sites More sharing options...

Yes 194’s for the license plate lights Link to comment Share on other sites More sharing options...
Barney Eaton Posted January 12, 2021 Share Posted January 12, 2021 If you are changing to LED bulbs they do not create the heat of an incandescent bulb so if you can find a chart that converts SAE bulb numbers to LED you can go to brighter bulbs. You can also do a Google search for bulb manufacturers like Sylvania and their catalog will help you select a brighter bulb. Link to comment Share on other sites More sharing options...
