2018 Sequoia Headlight Conversion Issue

I did the Sequoia Headlight Conversion on my 2007. I ordered them from The Retrofit Source and everything has worked fine for the past 10 months or so. This morning my right blinker started hyper-flashing and it turned out to the front right one not working. Given these do not have a serviceable bulb (that I can tell), what is the fix on something like this? Everything else seems to work fine, just the front right blinker not working. Any advice on how to check/fix this?

 

If they don't use a bulb and are just LED, then I'd check the wiring.

 

I am at work right now, but will put a meter on the wiring when i get home. I did look at the conversion harness where the signal connector is plugged in and it is indeed still plugged in. Ill be able to tell pretty quick if the issue is internal or external to the headlight.
For conversation sake, what if the issue is internal to the headlight? is there a fix for bad "bulbs" (sorry not sure what the correct term would be here).

 

Easy way to trouble shoot if it’s external wiring or internal headlight issue is just flip flop the headlights if you hyperflash follows the right one to the left side then you have a headlight issue

 

Yep like ^he said this is the best way to determine if it’s a headlight or wiring problem, if this end with a faulty headlight hurry up and contact seller before the 12 month factory warranty window close/expires

 

it was indeed a wiring issue. Looks like some moisture worked its way in the turn signal connector and corroded out the wire terminal. For now, i have a jumper hooke around the connector until i can get this harness taken care of. Thanks for the suggestions.

 

Clean the metal contacts with isopropyl alcohol and remove all the contamination, apply dielectric grease to metal pins and if posible a little bit of vaseline to all rubber seals to avoid them getting dry and cracking letting water pass through and put everything back to its place and you should be good, in recommend you to do the same with the good side to avoid the same issue in the near future.

 

I had this harness made for me. They are stepping up and fixing it. Since these sequoia lights do not have a dedicated signal bulb, the connectors used in this conversion harness replicate the signal bulb socket. I don't think this design allowed for the use of weather seals for the wiring. They did inform me that the fix would include an updated connector which i can only assume is now water proof.
