Please check the plug type of your headlight on your vehicle, whether your vehicle requires a set of warning canceller (canbus-driver) to prevent on-dash errors.
Upgraded heat sink cooling method without fan
Instead of turbo fan, one-piece integrated has better heat conduction. 6-piece flower heat sink design offers wider dissipation area to dissipate heat away from LED circuit quickly.
There will be no yellowing, hazing or micro-cracking on your plastic lens due to high heat exposure, also no fan fault or noise problem
