Why we released the mini projector bulb?

Reflector headlights have been around since the beginning of automotive headlights. A reflector headlight consists of a bulb encased in a steel bowl. When a reflector headlight works, the bulb source will filled the bowl of the mirrored housing to reflect light out onto the road. The result is a stream of light that comes out of the bowl in the direction that light is pointing.

With advanced technology and numerous vehicles, the original halogen bulbs can no longer meet our needs. People are bored with the dim light output, high power&overheat, and short lifespan. Manufacturers have developed many LED bulbs on the basis of halogen lamps, solving problems such as brightness, color temperature, power and service life. But the low beam cutoff line is still a problem. Unless you upgrade the reflectors to projector headlights, but that's a big expense.

Therefore, we developed a bulb with a mini projector at the front, so that everyone can upgrade the reflector headlight to a projector headlight at an affordable price. uilt with a mini projector, COLIGHT mini projector bulb shoots a perfect cutoff and bright white light, so that you can see far enough down the road to react to obstacles or avoid animals, and won't blind oncoming drivers.

The advantage of the mini projector bulbs:

1. Perfect Low Beam Cutoff and even light performance, no glare

Equipped with an innovative low beam shade cup and a micro-optical projector(lens) on the top, it enables the low beam to show a clear cutoff line ahead. In a typical H4 bulb application, only about 30% of the raw lumens are projected on the road as forwarding illumination. With this special optic, about 90% of the lumens will be projected onto the road. The micro-optical projector(lens) is responsible for the illuminating angle and amount of the beam pattern, can reduce light loss, maximize the light-gathering ability, making the maximum lighting length up to 150m. This feature is an unparalleled performance advantage over other H4 LED headlight bulbs.

2. Free switching between LHD and RHD modes

You can use the bulb Y6, Y7S and Y9 plus in both Right-hand-drive countries and Left-hand-drive countries. The original set is LHD mode, if you need to use the bulbs in UK or Japan, you can remove the big low beam shade cup, and you will find an iron piece engraved with L/R, flip it horizontally and assemble all the parts to get the RHD light mode. That's a 3min modding process, everyone can do that.

3.Better cooling performance and longer service life

All  mini projector bulbs are made of aluminum lamp body. It quickly transfers heat to an unparalleled pure aluminum base, which dissipates heat in seconds, maintains the operating temperature at about -40 ° C to + 80 ° C, effectively reduces light attenuation, and can reach a lifespan of 55,000 + hours.
