Frequently Asked Questions

Can I install my relay under the hood?
This is not recommended. FCKLightBars recommends installing the relay in the cab of the vehicle to protect it from extreme temperatures and moisture.

My light isn’t working. Should I disassemble it and troubleshoot it?
No! FCKLightBars are precision assembled in such a way to ensure no moisture can get into the light. Disassembly can destroy this seal and will void the warranty.

Can I mount my light vertically with FCKLightBars supplied mounting brackets?
FCKLightBars mounting brackets were designed and tested assuming the light is installed in the horizontal direction. Installing lights in the vertical direction could cause premature failure of the bracket.

My S1 & R1 Series lights have condensation in them!
The low power versions of all A-Series lights use a diffused lens that has a cloudy appearance, especially when compared to the lens in the high power versions of 3D Series lights.S1 & R1 Series products are fully sealed against moisture, so please be assured there is no moisture in your light.

Can I run my FCKLightBars light with a 14 volt A/C signal?
No. The FCKLightBars were designed for DC voltage. Lights operated at 14 volt A/C may not be damaged, but could flicker or appear dim.

Can I run my FCKLightBars light in an A/C wall outlet?
No! FCKLightBars are designed for DC voltage. Connection to an A/C wall outlet will very likely permanently damage the light.

When I connect my light directly to my battery, it is at full brightness, but when I use a long cable to install it, the light is dim. What is wrong?
You need to make sure you are using an appropriately sized gauge wire for your installation. This is especially important if using a long wire from the battery to the light installation. If the wire gauge is too small, there will be significant voltage dropped across the wire, preventing the light from powering up fully.

I see the current draw in the catalog, but what input voltage is that measured at?
All currents shown in the catalog assume a 13.8Vdc input voltage, which is the typical voltage of a fully charged automotive lead acid battery.

I connected my light to my car and it doesn’t work. Now what?
Several items could be preventing the lights from properly working. The below items can help in troubleshooting.
Try connecting the wires of the lights directly to a fully charged car battery. If the light works then there is a problem between the battery connection and the light. Potential problems include a faulty switch, faulty relay, insufficient thickness wire, and improper grounding.

How durable are FCKLightBars LED lights?
See Our Tortured Video on our InstaGram and our Website.

What is the difference between the  Spot and Flood beam patterns?
The flood configuration can be visually identified by it's higher trough, compared to the spot. Our flood optic illumates at a wider beam angle, but does not go as far. The spot configuration can be visually identified by it's lower trough, compared to the flood. Our spot optic illumates at a greater distance, but does not reach as wide of an area. Both of these lights are great for their individual purposes, and if desired, they can work together for a perfect combination of distance and spread.
