Burned Tail Light Sockets

Interested in the cause-- running stock bulbs in the tail lights- decided to use LEDS and noticed that the sockets where burned around the light bulbs specifically the 7443 our outside light in the tail lights for an evo viii. Swapped out bubs none the less to led just to give them a try knowing I would need to make changes or add a resistor--but also thinking that the sockets wouldn't continue to heat up due to the low voltage draw of the LEDS-- 1 week later went to look at the set up and look for a place for the resistors, pulled the LED bulbs and to my surprise--the bulbs socket is melted literally destroying the LED bulb. So the socket with the wiring is burned as originally noted and that has caused the LED bulbs plug into the wiring to burn. I assume its excessive voltage (amps) draw melting the socket--anyone else seeing this? Fixes? thinking swapping the socket without addressing the issue will yield another melted socket--.

What tail light bulb are you trying to use and LED in. You do realize your tail lights have 4 bulbs each right?

Something is drawing too much current. Voltage is not "drawn".

Voltage is a pressure.
Current is a flow.

there is a big difference.

I had to resurrect this thread because
​I have the same problem..
My brake light socket on both sides have melted. I have yet to find a "Fix" and even worse, I can't even source a new harness. I've found a few for a Galant, but not a Lancer/Evo. I havent even found one on eBay. Ideally I would like to source a new harness, and wire in a fuse, relay or resistor, but I'm willing to splice a new socket in if I can find a replacement. Does anyone know where to find a replacement, or know of a different model with the same harness or sockets?
If anyone can help, it would be very much appreciated!

@WelDun1
There doest not appear to be a separate pigtail harness used. This wiring is all loom from what i can tell

Are you in need of this connector? Mitsu part no. MR472555?

No that's definitely not an Evo 8/9 tail light socket.

Evo 8 9 tail lights have their own harness

Notice how the socket shape is like a rounded triangle.

Yeah, ur right, the connector is the same, but I don't need the connector. I need either the entire tail light harness with that connector or just the socket for the bulb. As you can see in the pic I posted, the socket itself is melted/burned.

Well, since I started this thread some 11 yrs ago--and no one has found a solution. While the original showed signs of getting hot- I ran with it after swapping back the the reg 7443 bulb. I finally found myself with a burned out socket where the light wasnt working at all. Totally gone. Well dug around again, and its amazing what 11 years of info on the internet will get you.... Found the socket for the 7443--that the rectanguar shape our housings need-- not the generic square sockets. They happen to also fit a 2000-2006 Prius OEM, toyota socket. If you search for the 7443 pigtail and the triangular shape in images you got it... Since these harnesses are no longer available for the Evo VIII taillights--well $15.00 for two pigtails is a bargain..

I had tons of these wiring harnesses from making tail lights for the Evo 7 8 and 9. They were for sale and now are gone. It was all posted in the market place. The heat that is damaging your harness is coming from a poor connection. Poor connection causes resistance- which is converted to heat.
