Stay far away from these lights as they are absolute JUNK! When switching between beams (Hi/Low or Low/Hi), the light goes out for anywhere from 2-3 seconds, and at times, 15-20 seconds. The seller claims this is ok, but not according to NHTSA, who I complained to. NHTSA agreed these lights are NOT legal based on this design flaw. The turn signal, while a nice design, is completely dim and not visible. The adjustment rod came disconnected, and kept disconnecting every time my truck hit a large bump. Amazon should not be selling these lights as they are unsafe and complete junk! I've bought many aftermarket lights for different vehicles and these were the worst.
