1991 K5 light issue

[Roger Horton]

Hello all Happy New year.
I replaced all my exterior bulb amd now when I press my brake my front running lights come on. When my headlights are on and have Right blinker on the blinker stays lit. I replaced blinker tinker amd all fuses.
What am I missing?
Any help would be appreciated!

Check your grounds.

One or more of the 1157 bulbs is in backwards, or not seated correctly

Or there might be a 2057 bulb in place of an 1157..
They look the same,but the contacts for the filaments are opposite..
Usually this causes a "running light" to look bright,because the heavier filament comes on ,then the dimmer filament comes on when the brakes are applied..sometimes though ,this causes weird back feed ground conditions and many things act weird..

bad ground on right side, and the hazard switch is pushed in, but the hazard flasher is bad.
