LED interior lighting - weird problem
So I've been on this quest to get the best looking blue interior lights. I am crazy about the color blue and I wanted blue lighting inside my car. I first bought the crappy blue colored bulbs from Lightlens.com which sucked. Then I ordered these LED bulbs from Ebay which shipped from Hong Kong. I got these over the weekend and installed them and here's what happened:
First, the "festoon" bulbs that go under the dash (by your feet) worked fine, but were a little short. This was easily handled by simply bending the metal contact inwards and making it a tighter fit. The bulb only works in one direction, so I had to turn them around until the light came on. These are 36mm with 6 LEDs. They look real nice.
Then, I installed the wedge bulbs in the overhead dome light and the two dome lights in the back seat. Now these bulbs have 4 LEDs and are wider than the OEM filiment bulbs, so I had to file down the plastic around the outer edge of the bulb to make them fit. When I plugged them all in, nothing worked. I was stumped and thought that I must have broken something so I spent hours trying to swap bulbs, test current with a tester, etc. Finally I gave up and put all the OEM bulbs back in, except for the floor bulbs and now it works.
NOTE: when I tested the current of the wedge bulbs, they didn't read. But, when I pluggen one of them into the reading lamp, it turned on briefly.
I am stumped. Why don't these LED lights work in the overhead dome lights? I thought maybe it was due to the dimmer, but then I looked at the floor lights last night and they dim, just like the filiment bulbs!
Any ideas? If LEDs simply won't work in the overhead lights, then what bulbs can I get that give off a true blue hue and are bright and actually work and are safe?
