1.Canbus bulbs also not directly to fit all cars, sometimes error code or hyper flashing occurred ,please add resistor or cancellor or flash relay, the problem will be solved.

2.LED bulb is low power consumption,so counted by theoretical power but not actual power.Because the resistor on bulb so that actual power is much less than theoretically power.

3.LED bulb has resistance so that bulb will become hot when working while it not affect its performance.(If more than 170 ℃ for long time,some resistor maybe bulge while it not affect other work.

4.For the brightness,please refer to the luminous, higher value will be brighter.

5.H1, H3,H15 and D series led headlight(D1S D2C D3S D4R...) only has two wires to connect to your car,so you need to remove your orignal connector if you want to replace with our led headlight,or you need to buy extra modified wires to connect between our bulbs and your car.

6.3157 and 7443 have different designed base on different cars, some car just need standard base while some car requires CK base,ours are standard base,please be known it before purchase.
