Thread: What bulb replacement for dome light :(

  1. #1

    Default What bulb replacement for dome light :(

    Hey guys I feel foolish having to ask this, but what damn bulb is in the 80s dome lights? I am looking for an led replacement bulb. Just have the typical dome light with the map lights on the corners. It shouldn't be this hard to find the bulb but ford have to change so much junk it seems and it's very frustrating trying to find an led bulb equivalent.

    According to the owner manuals for a Crown vic. It shows bulb 561.

    I've swapped nearly every bulb in my Lincoln with LEDs, and while your Mercury might have fewer lights it probably doesn't have different lights. In my experience, most every bulb that isn't behind the dash/instrument panel can be swapped out with either a 194 or 1156 socket replacement. The 1156s are for things like cornering and reverse lamps, the trunk light, and both map lights. The 194s go pretty much everywhere else, including the dome light.

    One thing to look out for with LEDs, which you may already be savvy to, is the color temperature of the light. A warm white, or lower temperature, will look closer to stock incandescent. I found with my black interior, though, that a cooler white ended up making the car feel a little less cave-like. And, of course, there are all sorts of colored options too.

    Edit: Based on Tom's answer it looks like non-Lincolns may be different, so disregard what I said.

    I remember two variants for the dome light center bulb. Check which type you have then proceed from there. Can always source a different dome light if your current one does not offer a LED alternative.

    One that looked similar to this:


    And one that looked similar to this one linked:

    That one looks to be a 168 or whatever. Those are probably also what's in the opera lights. ONce upon a time, I replaced every single exterior bulb in my Town Car. I believe '89 and up used the blade socket style bulbs.

    Anyway, Ford got lots and lots of mileage out of that damn dome light. They used that in pretty much every damn vehicle they made. From F series trucks to 70's barges, you name it.

    There is a lighting schedule in the back of the owner's manual if you have one still

    Absolutely what 87gtVic said. If you don't have the owner's manual with lighting schedule that gadget73 mentioned, pop the cover off the dome light to figure out which of the two styles you have. There may be a model year breakpoint for when one style was used over the other, but I haven't figured it out.
    My dome light on both of my '91s had the 561 bulb (562 should work as well, http://www.grandmarq.net/vb/showthre...l=1#post699544), but yours may take the 168 or 912.
    561/562 LED is available, I have LED in both of mine.

    Also, if you haven't found already, there is a clear dome light lens available from LMC Truck, part number 47-4291. https://www.lmctruck.com/1980-96-for...ome-light-lens It matches the light covers in the door/armrest nicely (if you have that option). The fit on mine is a little tight, but your results may vary.

    I second the LMC truck one. I like it. Does fit very tight. I dont want to mess with it for fear of snappage.

    Here's a pic if it helps, I know it's not a 164, or a 906 which according to auto part sites it is. This is what has me confused, so I'm guessing it's either a 168 or possibly 561? I went on LMC actually to buy one of their clear lenses that's why I'm monkeying with the dome light now lol but their led bulb is $14 for one, so I thought if I went on ebay and found some that would work cheaper and more than one bulb for the price it'd be a no brainer I like cool white led light, and I know a few led bulb brands I always bought on ebay that were great for my other vehicles.

    +1, 561. 562 should work as well.
    I went with a cheap LED 561 from eBay about 5 years ago and it's still going. With the clear cover it's much brighter than the incandescent.

    That is how I remember the stock one being in my 87 CV. I later swapped out to a thunderbird unit I found that is low gloss black. It is either factory or very well done by someone...reason I picked it from a junkyard eons ago...I believe it used a wedge type bulb.

    EDIT. I looked back into my notes and the black dome light housing I pulled was from a 1990 Cougar!



    That was with a factory dome light lens in case you are wondering.

    Thanks again guys! And 87vic I like that black housing, maybe I'll look for a replacement like that one, but I like that light with the stock lense more than if it was a clear lense. I don't know why, but if mine was black I would leave the lense how it is, but the chrome I think looks better with a clear one.

    Just by the way Red is considered the best color for not ruining night vision but still providing good vision.

    I highly recommend the LMC light lens. I have them in the cars. Huge improvement. I also recommend Diode Dynamics for their LED lights I have them in the Subaru. 3 year warranty. Very good quality. On their site they show the application for the Mustang. 168/194 $8 ea. You can pick the color and intensity.Far better than the Ebay garbage. You can also call them if you have questions. They were helpful with me.

    Some of the Chinabay stuff is OK, lots is not. the bayonet LED lamps that are in my gauges are flaky. One of them flickers badly, need to see if I can find either something better or a way to repair it. Probably a bad solder joint, the physical construction on those are pretty craptastic.

    I like blueish white light, it's not so much to see better at night it's aesthetics more than anything give it a more modern look, still waiting on my bulbs to show up I'll post a pic when they are done.

    specifically why I don't like the blue-white. It looks too modern.
