My son said the front direction signals seem so dim. On both side only in the front. They take a 1157 bulbs
The back looks okay. Should I replace both bulbs. I wonder if the lens in the front is clouded
Causing the light to be show so dim. Rest of the lights seem bright. Some suggested the contacts in the socket should be sandpapered or get a stronger or amber colored bulb

Disconnect the negative battery cable, clean the sockets with abrasive cloth, and apply dielectric grease to the base of each new bulb. To keep body oil from getting on the bulbs, hold them with tissue paper. Clean/refurbish each lens and inspect the seal. Yes, replace both bulbs (same existing color).

Very good advice

Also try cleaning the lens as well
