N4 1 Pair H4 Car mini Bifocal LED Lens Headlight 1. Adopting a unique lens design, the light pattern has a low-beam tangent effect. The light pattern is concentrated and rejects astigmatism, making driving safer. 2. Using 6 high-quality CSP large chips, this LED bulb combination provides up to 300% brightness and 6000K white light vision. 3. Plug and play, almost 1:1 mini design, using external drive structure and ultra-thin and short radiator, very suitable for most car casings and original sockets. No need to change the original cars lampshade for more convenient installation. Beautiful. 4. The drive solution uses an external constant-current intelligent temperature control module (intelligent control of current to maximize the effectiveness of LEDs, protect car lights and improve driving safety). 5. The lamp body is made of die-cast aluminum, and the lamp bead substrate is made of high-quality copper sheets, which has better thermal conductivity. The substrate and the aluminum lamp body are closely combined and in complete contact, allowing the temperature of the lamp bead to be quickly and efficiently transferred to the bottom fan. The heat dissipation effect is greatly improved. A hydraulic fan is used at the bottom to make less noise and extend the product life to 30,000 hours. 6.
