I tried replacing my turn signal/running lights with LED's since Im driving more in the dark hours lately and what a show they put on. I got the rears to work but at first the side markers decided to join the fun,I wiggled the plug a bit and it turned off. OK happy with that move to the fronts and install them and all the lights come on at once-front turns-rear turns-side markers. WOW!! Whats going on. The only difference I could see was the contacts on the base looked like cat eyes instead of dots. I replaced all my originals and everythings back to normal. Any ideas. Thanks. Dean

The car's original flashers need to be replaced with electro-mechanical type. The original ones depend on current draw. At X current, it flashes at Y rate. If X is less then a certain threshold it will stay always on.

Two prong ones are part# el12. Don't forget the hazard one too.

Only downside - with original setup when a bulb blows the flash rate changes. With this flash rate will be consistent regardless so you have to do your own bulb checks.

Careful, this was probably a very bad move. Almost all of them on the market are unsafe junk. There are no legitimate/safe/effective ones available for the front park/turn lights, and the one and only item that works safely and effectively in some brake/tail lights is this one. To make them work correctly you'll need a non-load-sensitive flasher (that is this one).

Not only can the (many, many, many) brands and types of unsafe junk cause the kinds of electrical backfeed weirdness you experienced, but they don't actually work correctly/safely in terms of providing the right amounts of light through the right range of angles, and the right ratio between bright and dim modes, and their output drops off severely with prolonged use, etc.

In the coming years we will see a growing number of good (safe, effective) LED retrofits, but we're only just at the beginning of that timeframe right now, even though the fast-buck artists have been bringing in the trash from China for years.

Not only what Dan said, but I did some experimenting of my own with LED replacement bulbs, and found that most of the LEDs weren't discernibly brighter, nor faster, just harsher.

You may be better off with the *correct* brighter incandescents.
My 2 cents

This gets my vote over LEDs in taillights.

The Philips LEDs I linked are really quite good (astonishingly so, in fact) in just about all the old Mopar tail/brake lights I've tried them in so far. I do recommend them. If you want to stay with incandescent, then order these specific ones.

Thanks for all the help guys. I removed them almost as soon as I put them in. I dont think Ill be going with them any time in the near future. They did look annoyingly bright so I will look for the brighter incand. I wasnt aware there were brighter among those. Learn something new daily. Thanks again.

To be clear about it: for several good reasons I actually recommend the (linked Philips) LEDs over the incandescents.
