They work great! Brighter than oem bulbs. Absolutely no hyper flashing. I can even use these as DRL.
Long story short I had to replace my front turn signal lights which on a Gen 2 Toyota Tundra is also the DRL- Daylight Running Lights. I purchased some inexpensive LED’s and the hyper flash started. I then purchased very high end headlight assemblies thing this would solve the hyper flash. I should have read the small print that these top of line lights utilize the stock bulbs for turn and DRL! I then scoured the internet for fixes but did not want to install high heat resistors anywhere online and especially in my plastic turn signal flash module under the dash. I came across these new LASFIT bulbs and decided I had nothing to lose. For around $60 bucks they solved my problem! So I purchased two more for the rear of my truck to match the excellent brightness!
As promised, new LED front turn signal bulbs work with no hyper flash! I’m thrilled. Would recommend over the standard bulbs.
The bulbs worked for a day after I installed them. Ever since then they have been causing the car to hyper flash. Headlight assemblies are starting to get moisture in both headlights as well when they have never had moisture problems before. The new bulbs were installed correctly and double checked.
Hell Jerry,
Thank you for bringing this to our attention, and we're sincerely sorry for the inconvenience caused.
This is actually the first time we've encountered such a situation, and we are keen to investigate further and assist you in resolving it.
It would be great if you could send us a short video of the hyper flash and moisture problems, so we will offer a solution.
Also, please remove the dust cover and turn the lights on for about 20-30 minutes till the moisture is gone completely.
After that, please put the dust cover back before turning off the LED bulbs, then it could be fine.
