FAQ

Which color LED should I use?

For the most vivid color and best results the LED color should be the same as the lens color. If a white LED is used behind a red lens some of the visible light is filtered out and the light will have a pink tint to it. If a white LED is used behind an amber lens the output will be higher and the color will be bright yellow.


Turn signal issues with LED bulbs

LED turn signal lamps will not flash with thermal flasher units due to their extremely low current draw. Some cars indicate this by increasing the flash rate of the turn signals, some do not flash at all. This can be remedied with load resistors wired across the turn signal bulbs to simulate a filament bulb load. One way to test this is to pull out one of your blinker bulbs. If you get a bulb out warning or rapid flashing, you will need load resistors. 

Load Resistors:
A 6 Ohm, 50 Watt resistor can be connected across the turn signal wire to simulate the load of 1 regular filament bulb (2 Amp load), a 3 Ohm 50 Watt resistor can be connected across the turn signal wire to simulate the load of 2 regular filament bulbs (4 Amp load). This will solve LED related turn signal problems such as hyper flashing, no flashing or burnt out bulb indications.

Connection Instructions:
Using the 3M 804 splice taps, connect one wire to ground and the other wire to the turn signal wire. You do not have to cut your car's wires. Squeeze splice taps with pliers. One Load Resistor required for each turn signal bulb. No instructions are include with these kits. 

ELECTRONIC LED FLASHERS
This problem may also be remedied with an electronic flasher, these units are not available for all makes of vehicles. Many vehicles have two blinker units, one for hazard and one for turn, so locate both by sound output. It is not always necessary to replace the hazard flasher.


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). This can be remedied with our 25w load resistors to simulate a filament bulb load. One way to test this is to pull out one of your bulbs, if you get a bulb out warning you will need load resistors. 

Bulb Out Warning Fix:
These 25 Ohm, 25 Watt resistors can be connected across the turn signal bulbs to simulate the load of a miniature filament bulb. This will solve LED related burnt out bulb warnings in your dash board display. One resistor is required for each bulb. Optional gel filled moisture resistant splice taps can be purchased for simple installation.


What is the difference between Warm White and Cool White?

Cool White
These LEDs have a slight tint of blue to them. They are rated at 6,000-8,000 Kelvin. These bulbs are a great match for most stock and aftermarket HID headlight systems. 

Warm White
These LEDs are closer to the color of a standard incandescent bulb. They are rated at 3,000-4.500 Kelvin.


Which LEDs bulbs are brightest?

Output greatly depends on the application and the intent of the installation. Our High Power and SMT bulbs are the brightest we currently offer. In most cases the higher number of diodes the bulb has the brighter the output.


Are the bulbs standard size?

All our bulbs are standard size and will fit the application it is replacing.


Do your bulbs have dual intensity?

All our 1157, 3157, and 7443 bulbs have high and low output. They will get brighter when the brake or turn signal is applied.


Will LEDs work with the dimmer?

Yes LEDs will dim just like a standard bulb.


What bulb type or part number does my car take?

Sorry we cannot advise on which bulbs your vehicle or application takes.

Please see our LED and Fitment Guide.


Can I replace my headlights with LEDs?

Recent developments in LED technology have paved the way for a new generation of bulbs that can be used for headlights.
