LED bulbs has longer life-span is it? I considered the above as well but hasn't change since it doesn't last long..

Theoretically LED bulbs have much longer life span, and also more resistant to damage than halogen bulbs.

Avoid the COB LED bulbs because low focus and more glare.

What's COB? Sorry, not too well verse with cars accessories.. hehe

Chips On Board (COB) LED looks like this:



If you retrofit them into a reflector-type headlight, you run the risk of blinding oncoming drivers because the light pattern is scattered.


My advise for buying LED bulbs
- the LED chips must imitate halogen bulb filament like below so that you get light pattern that's close to stock halogen bulb



- rotatable base to allow adjustment within housing
- all-in-one kit preferred, no dangling LED driver
- you may need to purchase aftermarket dust cover if the bulb is too long. this is to allow good air flow around the fan.

- fanless design may be less bright than fanned design because fanless design poor cooling causing LED to shine less to prevent overheat (I can't confirm this)
