We do not rate LED wattage because….

The operating voltage of a vehicle should be a range but not a fixed number, when we say car’s voltage is 12VDC, which means the voltage range should be kept between 10~18 V(18V is the highest possible peak voltage) and the average is approx. 14.6V, usually the standard of our products is 14V for CAR,...

How LED brake bulbs operated in dual intensity?

All of our Tail/Brake bulbs achieve dual intensity modes (1157 3157 Bayonet, 7443 T20 Wedge) by turning all of the LEDs on dim or all of the LEDs on bright, all of the LEDs are always lit when either mode is active, and the normal design we set the brightness in approx. 1(normal emitting) :4(

Viewing Angle and Brightness

Wider viewing angle, lower brightness, vise versa. We cannot recommend which type would work best in your vehicle because it depends on the size, shape and depth of your bulb housings. The wide angle bulbs usually work best for most vehicles than narrow angles.

Dash indicators reporting burnt out bulbs

 LED bulbs may cause some newer vehicles to indicate a bulb is burnt out (because of their low power consumption, car computer misjudge the bulb is burnt). Some cars indicate this by increasing the flash rate of the turn signals, some turn on a bad bulb indicator. The only fix for this is to install...

Turn signal “Hyper Flash” issues with LED bulbs

       LED brake/tail lamps will not flash with stock flasher units due to their extremely low current draw, the turn signals may flash faster than normal ( called "Hyper-Flash"). These installations will require an electronic flasher unit. Try to find flashers designed to work with LED bulbs, they will say "LED compatible". Often...
