Headlight issues

Ok guys need some help here please. I have a set of spyder headlights that have been in my crewmax for a couple years with no issues until now.
Bright lights work fine but bright indicator is not on.
Lights go out when I hit dimmer switch but then the bright light indicator comes on.
I’ve Changed headlight relay and dimmer relay. No fuses are blown.
At first it just wouldn’t dim when I hit the switch but then a day or two later lights go out when I go from bright to dim. Both bulbs in each headlight work including the DRLs

 

Sounds like this might be something internal (headlight). Have you tried using another headlight to see if the problem persists?

I would probably try to rule out any issues that might not be due to vehicle electrical first, then assume it may just be the headlight going out (since you stated you have had it for a couple of years).

 

Sorry, it’s both headlights having this issue

 

So High beam is on, but High beam indicator on dash doesn't show.
Dimmer switch turns on High beam indicator.

Have you traced your electrical to make sure nothing has been torn?

 

Correct but when I try to dim them the light go completely out and the high beam indicator comes on. I just drive it and the dim light came in for like five seconds then went off. They seemed really faint. I have not checked any wires yet.

 

My bet is those Spyders are no bueno. Get a cheap factory headlight and do a swap then check hi to lo function.
