Light Issue

Hi, Ive owned my 2005 Tacoma for over a year and just noticed this today. When applying the brakes the odometer, radio and clock lights dimmed. I usually drive with the headlights on during the day but today with them off i noticed this. Turned the headlights on and no change in those lights. I thought maybe I had a brake or turn signal bulb out but that all seem to be working. Any ideas? Thanks

 

Autozone will check your charging system for free in the parking lot. My suspicion is that alternator or battery is failing. Be sure and carry jumper cables you will probably need them soon. It could also be corroded ground connection, corroded battery cable, or corroded battery terminals.

 

Thanks, good advise. I'll take it to AutoZone and see what they say.
