1:1 Size of the Halogen Bulb
Boslla T20 7440 7443 LED bulb has the same size as the original 7440 7443 halogen bulb. Also almost the same emitting point on for more focusing lighting.
3-Gen 3030 SMD LED Chips
Each LED diode has a 15 pcs dual-lighting source emitting in 5 directions, 100% covered with Phosphor Film which brings more saturant lighting sources.
Non-Polarity Design
100% plug-and-play installation, fit both CK and Non-CK socket. You don’t need to pay attention to positive or negative plug (+/-), just like a halogen bulb.
Very bright, completely extinguished, perfectly suitable for Ford edge parking lights, it is now white with turn signal lights turned amber, looks very well done, you can see how long they last.
Works as expected. Every light in my car has an LED, many of which are of this brand. Just installed, but the brand’s taillights have been in use for a year.
Cool
Great lights. Super bright.
I absolutely love these in my 2007 Chevy Silverado! I hate super flash, but I can fix it. Most vehicles can use flash modules or resistors to correct it.
Love this dual-color bulb.
These bulbs are great. They work well, the white is not too bright, but the amber is very bright, a great improvement over the original halogen lamp.
They are very bright, especially white, and can provide extra light to the sides. I will definitely buy it again.
great product what a differance, these bulbs are exactly the same as described, and are actually better than expected.
I had to replace the turn-back device on the truck that I have used for many years. These are the brightest… if you ask me… I am satisfied with longevity.
