How do I find out my bulb size?
Head over to our Shop By Vehicle page for our bulb guide. Even though a lot of time was put into our bulb guide to ensure 100% accuracy, it is possible some of our sources were inaccurate at the time of creating. And so we recommend checking the owners manual, getting a second source for your bulb size (such as your local dealer or auto parts store), or by removing the bulb. Removing the bulb is a 100% must if you have aftermarket headlights, as the bulb size can change by doing so. Once you know your bulb size it's just a matter of selecting either your desired HID or LED kit.
Does my vehicle require decoders?
You can learn more about decoders and why they may be needed here, but in general; we recommend decoders on your LED kit if you drive a European vehicle, a Dodge, Ram, Ford, Jeep, or Chrysler.
Should I buy an HID kit or an LED kit?
Both are great options and so it mostly comes down to personal preference. Here at HID-Power, we run both HID's and LED's in our vehicles. Learn more here.
Which HID ballast should I choose?
We recommend CANBUS ballasts across the board, we have 35w and 55w options for those who want the most amount of light. They are more durable, and smooth out the power input and provide resistance. While most vehicles do not need this at all, it can still help provide a more reliable operation. CANBUS ballasts are more expensive however, and luckily they aren't a requirement for most. But if you drive a European car, a Ford, a Jeep, Chrysler, or a Dodge, you will more than likely need CANBUS ballasts. We do not recommend 55w ballasts for the fog lights. Learn more here.
Which LED kit should I choose?
It mostly comes down to how many lumens you want and how much you're willing to spend. Our 3CC kit has CANBUS built-in and so it is a great option for European cars, Dodge, Ford, Chrysler, and Jeep. However, if you want to run one of our other LED kits with higher lumens (the 3CC kit has 6,000); you can but you'll need to use our C-Series Decoders as well if you own any of the above mentioned vehicles. For details on each kit, click here.
What is your brightest kit?
We have 35w and 55w HID kits, the latter being brighter, but due to the extra heat they are not recommended for small plastic fog light housings, they are fine on large sized headlights. Our brightest LED kit at the moment (June 2018) is our APX kit boasting 9,000 lumens.
What HID color is the brightest?
We recommend 5000-6000 kelvins for maximum light output. But if you want to sacrifice some usable light (more UV light which is invisible) for a cooler color, that's totally fine. We recommend a maximum of 8,000k if you still want a blend of good light output and blue color. Above 8000k, and especially above 10000k, and you begin getting less usable light. Learn more here.
What is CANBUS?
What is a Bi-Xenon and a Hi/Lo kit?
This only applies to dual filament bulbs, which are bulbs that utilize high and low beams in the same bulb. A hi/lo kit only upgrades your low beams, the HID bulb is in the center of the bulb with a halogen high beam attached next to it. The Bi-Xenon upgrades both high and low beam to HID by using an electromagnet to change the physical position of the HID bulb for the low beam as well as high beam. This moving bulb adjusts the focal length and adjusts light output to a wide angle for high beam, and a tighter more focused light for low beam. It's important to note that because standard halogen bulbs do not require specific polarity, meaning the power and ground side of the bulb do not matter; with HID's, specific polarity is usually required, and so a plug can be flipped if it does not turn on the first time. This can be a problem with dual filament bulbs since they can only be installed one way, and since HID's are designed with the most common polarity configurations. But because polarity does not matter for halogen bulbs, some manufacturers are inconsistent with standard polarity configuration in the connectors. In this unfortunate situation, it is important not to blame the HID kit, and realize that the wires in the connector on the HID plug need to be switched from one side to the other. Note that manufacturer errors such as this are rare, but they do happen.
Why are my lights flickering or shutting off?
Since HID and LED kits use less power than the bulbs they replace, it can be a problem if your vehicle comes with a CANBUS lighting system, as this will think your lights are out causing them to flicker. This is common on European cars, Dodge, Chrysler, Ford, and Jeep. Other reasons outside of this that can cause issues such as this are:
1. Daytime running lights (disable if you have DRL's - then test again.)
2. Poor battery
3. Poor alternator
1. HID Relay Harness – The relay harness will allow the ballasts to draw power directly from the battery eliminating most low or fluctuating voltage problems.
2. CANBUS ballasts or LED decoders – These will provide extra resistance to the vehicle's circuit, meaning the CANBUS lighting system will no longer detect the deficiency in power and the lights will function as intended.
3. Load Resistors (rare when needed) - These help the HID/LED lights replicate factory power consumption. Resistors are a popular and universal fix to add more power to the circuit. Resistors do get hot during operation, since they covert power to heat, but this is not a concern if they are properly mounted away from plastic, and only hanging freely or touching metal surfaces.
Do I need a relay harness for my HID kit?
This is vehicle specific. But in general, if you have installed an aftermarket HID kit and are dealing with flickering issues due to insufficient power supply, a relay will likely fix your problem. The relay will power your HID kit directly from the battery to help keep the lights on.
How does warranty work?
