This modification can be done even on the most limited budget, and will greatly improve the look of your interior at night. With my gray interior, and stock bulbs, the carpeting and seats looked yellow at night with the dome lights on. With the LED modification, it is MUCH brighter, and a nice white light, with just a slight bluish tint.

No splicing or cutting of any wires is necessary, as the LED panels come with an adapter to fit the stock Fiero light bulb sockets.

You can purchase the LED panels from the DealExtreme website, you your favorite LED retailer. If you purchase them from DealExtreme, shipping is free, but be prepared to wait! The orders come out of China, and can take a few weeks to arrive. (I think they take the proverbial "Slow boat from China"! )

These are the LED Panels that I used:



I chose these panels, as they are a perfect fit, and match the size of the Fiero Lenses nicely:

Also, I find they are better, due to the fact that all 8 LED's face down, giving you much more light. The LED's fashioned into a bulb like round housing, will have just 2 of the lights facing down, and the remaining 8 facing up or to the sides.

Looking at this bulb, you see that only 2 of the LED's will face down when plugged in, the rest are pointed in every other direction, except where you want the light to go



First start by removing the 1st and last lens from the dome light assembly using a small screwdriver. You will see a small notch for the blade of the screwdriver in one end of the lens. Be careful, as the plastic is brittle from age. If you do break off one of the tabs that hold the lens in, you can glue the lens back in place. The LED bulbs will probably never burn out. Try to keep 2 of the good lenses in the 1st and last light, so in the future you can get to the screws to remove it, in case you do need to change out an LED, or work on the wiring.

Behind the 1st and 4th light, there are 2 small bolts that needs to be removed. There are also 2 screws where the end of where the sun visors click into the dome light assembly, remove those as well.

After removing the assembly, drop it down, and unplug it from the wiring harness, and take it somewhere to work on it.

Start by Removing the current bulbs, and plug in the sockets included with the LED's that fit the Fiero bulb sockets, and plug the other end of the adapter into the LED panel. Repeat this for the other 3 bulbs. Now it is important to test the lights. Either use a 12v bench tester, or just plug it back into the car. Chances are some of the LED panels will not be lit. LED's need the proper continuity for them to work. For the ones not working, simply remove the plug from the light socket, and insert it back in the other way around. Once you have all 4 lights working, you can unhook it from the 12v and go back to work on it.

I chose to put all the lenses back in at this point, and I used a little silicone to hold the LED panels in place attaching them right to the lenses. Make sure they are centered in the middle of the lenses. If you do not want to silicone them in place, you can tape them from the back, or devise another way to hold them in place.

Note: When replacing the lenses, look at the tab on the lens, and the notch in the assembly. One tab on the lens is larger than the one on the other end. The are meant to go back in, only one way.



That's about it! It is a simple 15 minute project, that will definitely make for a brighter, much nicer white light, and use far less energy when you leave the doors open for a long period of time.

Here is a dome light assembly with 2 stock bulbs, and 2 LED panels. It is quite easy to see the difference!



And again, it is a mod that can be done on even the most limited of budgets!



Here is Fiero after the LED conversion:

You can actually use the same LED panels, as the ones above. They use the same plug. The LED panels have Peel-n-Stick tape on the back to stick them under the dash.

If you would rather use a standard bulb type LED, This one should work... I have not tried it yet, but it uses the same plug.



A pair of them is $5.

Again, I have not tried this one yet, so I am not sure how bright they would be, or even if it will fit the Fiero socket 100%. I just ordered a pair, and wait for a few weeks for them to get here, and let everyone know

@ ALEX: Do not order the LED panels, I ordered extra's, as you plan to powder coat my headlight buckets, and refused any payment. Thus I can at least give you something for the time and effort
