Good product, excellent price. Hope it will last a long time, but at least it is still very happy now.
This is by design, the white turn off during flashing makes the turn signal very obvious.
These are great bulbs. They are very bright. My only observation is that I want the amber to be as bright as white. …. But it is still very bright.
It’s been more than a year, and it’s still strong.
They are much brighter than the first generation of LED bulbs available when I first replaced the incandescent bulb. This is exactly what I need.
For those who do not like to turn on the headlights in low light conditions, white light can also be used as a daytime running light.
It continues after a year.
Now I like these bulbs. They are very good. I may have spent a lot of time looking for suitable bulbs to replace halogen bulbs. Fortunately, I found that this bulb prompted me to buy more products because this is their advantage.
These are very cool. I have a lot of problems, many new and old cars cannot see the signal lights. The problem was finally solved in this brand of car lights. These are bright at night or during the day. Both the white running indicator light and the yellow flashing can clearly let people know that I am turning and make travel safer.
Make my car look more classic. Love them!
These are so cool. It can be installed directly into my 2003 Suzuki without modification.
