Simple EL Tape to help renovate my old car

Here’s my problem:

I am renovating an old car that has external vanity lights on the rear windows. Back in the day, a small filament bulb with an inverter was used to power the light once the car was started. Due to the heat build up and vibration during the drive these bulbs fail within a year or so and the inverter fails at about 3 to 4 years.

Current solution found:

A couple of folks have been buying EL tape with an inverter and soldering it into the existing system after removing the original inverter and bulb. This seems to be a $50 solution (about 20 bucks for two assemblies) which comes from China and can take weeks to get here. Seems expensive, time consuming, and no easy support.

What I’d like help with:

This is my first electrical project. For each side, I need a 12 inch piece of white electroluminescent tape with an inverter that I can attach to the current electric system. I’d rather have some way to put a connector on it and the car electric system so I can join them without soldering. There isn’t anything fancy, no computer interface, no gps, no multi-color. You folks here seem to have a wealth of info and products, but I really don’t know what items to look at. Could someone help guide me? If I’m in the wrong place, could you point me in a new direction?

Thanks in advance,

Thinking about this, I keep wondering why there is an inverter. There are plenty of 12v bulbs out there. Why not drive one directly? Could you please give a bit more detail about the car and this particular feature. Without more information it is difficult to provide useful guidance. For instance, SparkFun carries a selection of EL tape, wire and panels and also inverters, but I can’t see how these would last since they are not built ruggedized for the automotive environment. Also, EL provides a nice glow, but for actual illumination you can do better. I’m thinking that an LED string might be a better solution, but without seeing the intended use it’s just a guess.

Thanks,

Yea, would be helpful to know the Make and model of the car. Thinking it’s a Lincoln or similar that has the lights on the side by the rear window. Not really for illumination, just show.

Sorry for the delay checking back in. The 4wd electronics in my truck spazzed and I detoured to care for that.

Back to the car…

This is a 1987 Chrysler Fifth Avenue, M-Body style. Inherited from my mother-in-law and I don’t know when these lights were last functioning.

The lights are in fact for show on the exterior, they are ‘opera lights’ that originally used EL in the late 80’s and in the early 80’s it was a sylvania or GM bulb.

I’ve checked with the dealer as well as online groups and local auto parts houses. None of the original opera lighting options are currently made. These lights only come on when the car engine is running. They are in the rear side windows and are just for show rather than any useful lighting for entering or leaving the vehicle.

Since there is already an inverter on each side of the car for these window lights, I thought I would use a multi-meter to determine if my inverters are still working and just mod on a light replacement. The car wiring is already expecting to have an inverter there and lighting there so the infrastructure to hold it is present.

A discussion I found is here: http://www.dippy.org/forum2/index.php?topic=3137.15 And there is another similar discussion with more detail and pictures here: http://www.forfmjbodiesonly.com/classic … ht=glowhut

As I understand it from my research, the LED strip technology seems to show a distinct led bulb pattern when lit; whereas the EL Tape provides a uniform light.

The inverter is to get the car’s 12 V converted to something an EL tape could use.

The concern of vibration is a fact of life with cars and one we have to ‘restore’ as needed every few years. But this is nothing different than replacing old style filament bulbs that degrade as well. Again, this is all heresay on my part from reading about this problem. The thought is to find a lighting solution that is viable for years to come rather than pay exaggerated prices for that last bulb of old technology.

This is similar to converting the cooling systems using the old R12 coolant to the currently acceptable R134a. You can buy R12 if you can find it, but it costs over $100 a can and it takes 3 cans to fill the A/C lines/compressor. But the R134a cans are 3 to 4 bucks a piece. The feds tacted on huge taxes to make it unpleasing to go with the older coolant since it was thought to adversely affect the atmosphere. Or at least more adversely than the original analysis of R134a. But I digress. Been doing too much research on several car issues.

So I am looking for any guidance or observations from you folks because you all seem to be further along the knowledge curve about the newer electronics and lighting. Is there a better solution, should I get longer tape and make my own 1 foot pieces, is there better LED diffusers/double density lighting that would be better?

My apologies for the long response, but I sincerely appreciate your help.

Ok. I think you are on the right track. SparkFun sells EL material in different form factors that you can probably adapt. Measure the output of the existing inverter to confirm the SF material is compatible (compare to spec). If not compatible then you’ll have to replace your inverter with one that is. SF has inverters too.

Good luck w your project.
