Check the brand of bulbs. If they are two different brand they may omit different amounts of light.

Both bulbs are the same, and I replaced the socket of the bulb that has little light with a new one and I still have the problem, on the ground cable...Its attached on the driver side near the tail light with the bulb that is brighter, could it be this? I think ill go try relocating the ground between both taillights to see if it fixes it, thanks

is the bulb socket rusty/coroded that is what caused mine to be dim. warer can get to these fairly easy and cause them to do this.

i would not relocate the ground but disconect it and scuff it up and get good contact surfaces and reconect it and see what happens. i forget do the left and right brake lights connect and only have one set of wires running to the front or do they indivadully left/right have seprate sets going to the front. if ther conect to each other you may check the bright side conections. i may half to check out how they are wired on my car.

the connections meet up at one place and then it has a plug in connection that plugs to a harness that goes to the front.

Look closely at the bulb outside of the lens. They have two filaments in them. One for the parking light and the other for the brake light. (So, they bulb is double-bright when the parking lights and the brake are on.)

When you apply the brake and have your headlights on, are they all the same brightness?

If you have a crossed wire in the system, both filaments could get lit for a single-filament condition - which would make one look brighter than the other.
