Led bulb in taillight problems

So I ordered all clear taillights which means I need a red bulb. So I put some red led bulbs in there. They worked for a day or two and now they only work when I press the brake pedal. They won't come on as running lights. So I changed the bulbs again and same thing worked for a couple days now back to same problem. Only come on when I press the brake pedal. The running lights don't work. Wondering if anyone else has had this problem. It also doesn't work when I try and use the turn signal. Could just need a simple
Resistor or maybe it's a relay in the truck of some sort.

Help would be much appreciated. I'm sure someone else is trying to run LEDs in the rear

I just ordered one off eBay for 12 bucks. I hope this clears up the problem

What brand of LEDs did you use?
There are a lot of cheap leds out there that I would not trust, if they worked correctly at first, then started acting up, I would say that they are not very high quality leds.

I use leds mostly from vleds: Automotive LED Lights | LED Driving Lights | LED Lights For Cars

Where did you find the clear lights? I run the spider style led bulb and love it. Make sure u have the bulb for the right socket. Standard or ck I think are the two types of sockets. The grounds are in different spots. U can fix it by moving the wire leads on the bulb around.

The flasher operates the signals, NOT the parking lights / taillights.

Do the rest of the parking lights work? Do the dash illumination lights work?

What number are the bulbs?

Yeah all my other lights work fine. I just out my stock tail lights and bulbs back in and they are fine. So I'd must be something to do with the LEDs.

The bulbs are 3157

It _shouldn't_ matter (it doesn't matter with the better quality LEDs), but try turning the bulbs 180 degrees and reinstalling them. If that doesn't fix it, then I'd say yeah, the taillight / "dim" function of the bulbs has failed on both.
