I don’t think a capacitor will help much unless you put a diode ahead of it.
Or a low dropout regulator.

Even a resistor would help.

Any way to get inside? The LEDs probably run on something like 5 volts
or less, and the 68V is probably because they have a bunch in series.
if you could get inside you might be able to MacGiver something to work
on straight 12V.

I'm looking to do some interior lighting in a work van. I had the
bright idea of using the light strips out of a 4' LED fluorescent
replacement tube, 1600 lumen, 18w ($12 on ebay). I think it will work
perfect since it will be nice bright light over a 4' area, and is ultra
thin, and can just
The bulb comes apart easily. They are all in series, hence the high
voltage. Maybe I will try scraping off some traces and see what happens.

Maybe look at the voltage drop across each LED. Should be about 0.7
volts. So there should be about 20 to be forward biased per 14 volts
in a typical vehicle. Will probably need some resistor for each section
to limit current.

Have you tried changing the interior bulbs to LED? This should brighten up
the vehicle quite a bit.
You can buy several of these and mount them on the ceiling.
I found some LED under cabinet puck lighting at home depot that was 12v to
the pucks. I wired them up to the van power directly. Only issue is they
show alternator flicker. Have tried adding stiffening capacitance without
much result. Works but slightly annoying. The pucks were light enough to
This stuff is sold all over the Internet. It runs on 12v, works great, is
waterproof, and changes colors. You can also just set it to white. It's
super cheap and easy to work with, self adhesive.
