GZP Synapse white LED H4 bulb w/H4 plug

These LED projector bulbs feature state of the art SMD technology and have a heavy duty construction with, unlike conventional bulbs, a high resistance to torsional frame vibrations. The high power patterned SMD type LEDs provide maximum illumination. They come complete with socket adaptors to allow fitment in any headlight with H4, HS1, BA20D, T19, P43T or P45 base. High Beam is 1,500 Lumen at only 18 Watt low beam is 1,000 Lumen at only 12 watt, which is better as a common H4 bulb. Does not require the installation of a separate ballast as these bulbs feature a built-in rotary cooling fan.
