I went home and reattached all the wiring, blew the fuse again and abs light is back. @guybo what made you think that was the problem originally? Is this a common issue among these lights ? Are the lights toast or can I fix the wiring somehow ? Or better yet Should I simply return them under warranty for a new pair ? I Put them on Christmas time last year & Everything functions properly except the left side Valenti brake strip ( this is what is causing the fuse to pop every time I've determined) any insight would be appreciated. I saw somewhere on YouTube that if you re-wire the inside of the 3rd brake light to make the triangle solid instead of flashing when pressing the brake that helped a few people that were experiencing similar issues. What do you guys think about this ? Any electrical gurus in here that can lend me a hand

It really isn't the Toyota techs responsibility to diagnose the issue with the aftermarket lights so I don't know what more you expected from them.
If narrowed down to the left brake strip you either have developed a dead short someplace or the ballast for those ones is bad. I doubt rewiring the triangle is going to help anything in the left brake strip.
If you still have the stock lights then put them back on and get ahold of the vender or Valenti to see what they have to say.

I was more or less looking for something like this, not necessarily expecting them to actually fix my tail lights if that was the problem. Just something where I could have solid proof the valentis were the issue so I could bring it up with the vendor I purchased from and attempt to get a new pair

Edit: would it be matter if the 3rd break light is wired to the left (not working) side rather than the right (working)

I don't know the whats and whys, but I thought it was the aftermarket tails because... aftermarket.... The OEM tails are designed to last the life of the car and will if left alone. Aftermarket stuff is usually not engineered and produced to the same quality. That's why OEM stuff is always so expensive.

I hope you can suss it out though.

AHHH I see.


Yes, it would very much make a difference. Disconnect just the triangle and see what happens.

Doing a little update to this thread, I found the source of the problem. It seems when I hit that area on the road it must of loosened up the clips that hold the 4th brake light wiring harness in place against the back end of the cars body. I found the wiring harness had fallen out of place and landed on the top of my exhaust tip slightly. This caused the plastic around the wires to melt and some of the wires connected to eachother, I pulled all the plastic away from the wires and seperated each individual wire with a razor blade before using electric tape to cover each wire back up. Finished by generously applying the tape to the harness aswell, popped in a new 7.5 amp fuse and voila ! No more abs & traction lights, everything works as I used to however car handling seems to have been affected by driving with them disabled slightly... already getting a reimbursement from Toyota tomorrow for the previous “work” then I’ll have them check out the other issues
