Description

When your original halogen headlight becomes weaker and weaker, it's time to change. Choosing a bulb that is bright and owns a proper cutoff line is very important when driving in the dark. Built with a mini projector, this COLIGHT Y! Series H4 bulb shots a perfect cutoff and bright white light, so that you can see far enough down the road to react to obstacles or avoid animals, won't blind oncoming drivers. Let's see how it play.

PERFECT CUTOFF LINE & HIGH LUMEN OUTPUT:
In addition to your vehicle’s tires and braking system, your headlights are one of the most critical safety systems on your vehicle. No matter what season it is, we need to rely on the forward lighting systems in our cars and trucks to keep us safe. Let's ignore the fact that LEDs are brighter than halogens, the properly cutoff line is a very important safety issue that is frequently underestimated.

COLIGHT Y! LED headlight H4 bulb has an innovative big low beam shade cup with a micro-optical projector(lens) on the top, that 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.

Thanks to the excellent circuit solutions, it requires less energy to keep cool and keep power to the LED up. Just only 33w results in 3630 lumens of high beam output and 23W results in 2530 lumen of low beam output per bulb.

Before buying, you should realize this bulb can be only put in the H4 headlight housing without the projector, and the socket diameter should be large than 1.5inch. 

LHD/RHD SETTING:
Another advantage of the Y6 bulb is you can use it 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.

BETTER HEAT DISSIPATION FOR A LONG LIFESPAN:
The all-aluminum lamp body 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 30,000 + hours.
LED CANBUS decoder has strong decoding and anti-interference ability, which can make the current more stable, does not affect radio reception, does not interfere with radio wave batteries, keep supply to the led headlights bulb current constantly.

Before you install, you need to unscrew the bottom base, then insert the bulb in the correct orientation, fix the buckle, and finally install the bottom base. The entire process can take up to 10 minutes to complete. You can install it yourself without going to a specialist repair shop. We provide a 2-year warranty and provide quality service before, during, and after-sale.
