I recently purchased 1156 led bulbs for my coutersy lights in my 69 Beaumont and they wont work ! Tried the bulb on my battery with the base being negative and the post being positive and it works ? what gives. The lamp holder has 2 wires an orange and a white. the orange is battery positive and the white is the ground either by the door jam switch or the light switch . Has anyone had this problem with the led lights before ? I had the same problem with 1157 bulbs in tail lights. the brake light side of the bulb works but not the tail light side. Hope someone can shed some light ( sorry for the pun ) Again checked the bulbs with a seperate socket and battery, they work. plug them into my new grounded sockets in the car and no go. I used to like leds hope somebody has an answere !
I think some times you have to buy a lil kit to make them work . A buddy put some in , in his m benz and hadda buy a lil kit to make the bulbs work . He took out 194,s an used a led replacement , wouldn't work , got some little kit from Perf Omprov an works fine ..77.

led lights dont need resistors normally to work, i have found before that sometimes the base of the light needs massaging since sometimes you dont get contact in some sockets, i use leds where i work and since they mostly made in asia the quality of the base is suspect
Poke around this site easier then trying to explain it . tail lights not working could also be flasher related . 1/4 watt resistor in line would probably solve your issues
Turn signal issues with LED bulbs
LED brake/tail lamps will not flash with thermal flasher units due to their extremely low current draw. Also, with stock flasher units, the turn signals may flash faster than normal (Hyper-Flash). These installations will require an electronic flasher unit, available in our car bulb shopping category (for some vehicles) or at your auto parts store. Try to find flashers designed to work with LED bulbs, they will say "LED compatible". Often HEAVY DUTY flashers will also work with LED bulbs.
We offer some LED Flashers in our Tail/Brake Turn Signal Bulb category but we do not know which one (if any) will fit your vehicle. You will have to compare the pin-out of your flasher with the pin-outs of the flashers we offer, to see if we have a match, BEFORE you order one. Sorry but we do not have a flasher application list or the expertise to tell you which of our flashers will fit your vehicle.
Another fix is the installation of Load Resistors which are wired across (in parallel with) the turn signal bulbs to simulate the load of a standard filament bulb. We also have these available in our car bulb shopping category.
A lot of the LED bulbs are phase sensitive. They have to have pos. to pos. and neg. to neg. in order to light. With a 1156 you should be able to take the bulb out and give it a half turn and try it again. (The bayonet pins are the in the same position so that's an easy fix if it's the case.)
LED's are diodes, they only allow current flow one way. Make sure they are in correct.
I could tell the story of the customer who came in the shop after he decided to put LED interior lights in his late model Toyota. He then had his car towed to the shop where we put a dash cluster in to replace the melted one to the tune of about $3000 because he screwed up putting the lights in.

I cant see how you could put them in backwards anyway. they are replacement bulbs power comes in the pigtail + and is ground through the body. Unless your running positive ground it would be hard to mess up. A plastic dash circit board would require you to pay attention
The light works fine on a test battery. I can turn it 180 degrees in the socket and it doesnt matter it still lights! It wont light when I put it in my car ( which has the same socket ) Is it a ground problem and it so wht does the regular bulb work ?
I took my courtesy lights down from under the dash and found the problem ! the power wire ( orange wire ) was going to the ground part of the socket not to the end pigtail ! With incandesant lights it doesn't matter which side the ground goes to but it does matter on led's as you guys stated.... once I corrected the wiring voila it worked, thanks for all the input I am not sure where I got these from but I have never seen them this way before ! the power wire usually goes to the center electrode and the ground to the housing. Things that make you say Hmmmmmmmmmmmmmmm !!!!
Still Required for tail lights to trigger the flasher . I have herd of people running standerd bulbs in the front and LEDs in the rear and this has worked or a 20 buck electronic flasher vs a few bucks in resistors.
