Well, no idea on this one. But heres the background. Checked and replaced all bulbs, bulb holders for tail lights, (looked good) replaced one. So no idea. At one point it blew a fuse and half my side lamps went out (easy 5 watt fuse fix) now lights all work. but when I have just my "parking lights on" when I hit the brake they get brighter... And my high brake light is on all the time now..
I'm sure there is a ground issue some where, idk, any idea where to start?

If it were a ground issue you wouldn't have excess current, which is the result of brighter lamps, but a decrease. Your lights would dim as the result of poor ground.

Did you replace all the bulbs with the same wattage rating as the OEM bulbs?

If you replace a 5 watt bulb with a 15 watt bulb you may experience an increase in illumination, but only if the wire & the fuse can carry the current to support the 15 watt bulb.

Check that the ratings on both bulbs and the fuse are correct just to be sure.

Beware of autozone. I went back in and they said they were upgrading computer systems or something, and it listed the wrong bulbs. So DJ you were mostly right, they bulb was a higher wattage, so it would light up the 90 when I'd hit my brakes.
