Brights only

#1

I’ve replaced the relay and bulbs for my '92 Rodeo but only the brights work when I pull my dimmer switch. How do I fix this and what is the cause of this??


#2

Perhaps the low filaments are burned out on both bulbs?


#3

If the bulbs have been replaced then the dimmer switch could be faulty. I would check the system with a voltmeter before replacing the switch. You could have bad connections as well.

Sorry missed the changed the bulbs part.
