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

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.
