Brake lights are dim when applied

I have a 98' Tacoma, xcab, 4wd, when I apply the brakes during the daytime they are dim, not any brighter than just turning on the parking lights. Does anyone have any ideas what this could be?

Replace the bulbs and check the fuses.

 

Clean the contacts and grounds, if that doesnt work check the voltages. Incan bulbs will light poorly with low volts.

 

Grounding problem. Do the brake lights work at all when the tail lights are on? If the ground for the rear taillight assemblies is bad the brake lights will try to ground through the tail light bulbs. Sometimes that results in no brake lights at all with headlights/taillights on.

 

X2 These pretty much sums it up.

 

Thsnks for all the replys, checked the sockets on the bulbs, not in too bad of shape but cleaned them with contact cleaner and replaced with new bulbs. Still a litle dim so i disconnected ground cleaned and sprayed with contact cleaner and they are working great now. Thanks for the help!!
