Factory HID to LED Conversion kit with replacement guide

Do you want to convert your factory to LED bulbs? If so, you’re lucky because we’ve got the perfect guide.

This article will explain the factory HID to LED conversion and how it can benefit you and your business.

We’ll also provide tips on choosing the right LEDs for your factory and offer some advice on maximizing the benefits of LED bulbs. 

LED conversion is a simple process that can benefit your business in various ways. As the name suggests, HID lights use high-intensity discharge lamps.

This means they produce a lot of heat, leading to high energy consumption and blasting heat into the atmosphere.

Can You Convert HID To LED?

Can You Convert HID To LED?

Yes, you can convert HID to LED. Here’s how. HID stands for High-Intensity Discharge, the name of a particular type of light bulb, which actually was the first type of light bulb developed in history.

LEDs stand for Light Emitting Diode, which is a different type of light bulb that uses electricity to generate light instead of burning gas as it does with HID bulbs. 

But to make a long story short, you can use the existing HID ballast and rheostat (used to dim the HID bulbs) over your bike’s headlight and taillight and practically use the same wiring that you have now.

Also, in some cases, it is possible to skip the actual rheostat and wire directly into your existing connectors. But it’s wise to check if this will work before hacking into any of your bike’s electrical systems.

Can You Replace Factory Headlight Bulbs With LED?

Yes, but you should be aware of the consequences. Most OEM headlight bulbs have a factory warranty that is voided when the light bulbs are not OEM.

It’s important to measure power usage, color temperature, light output, and cost before making your decision. LEDs use less power but may not legally be used in some countries due to different safety standards.

LEDs dramatically reduce tail lights and indicators as well, just like halogen bulbs. Some have stated that LED tail lights are not replaceable, but there are at least 12 replacements for each standard bulb type. Check the forums for your car to get more information about your specific vehicle. 

LEDs can be easily removed from some headlight assemblies, so those may be available if you require replacement light bulbs for a specific purpose.

Aftermarket HID to LED Headlight Swap Steps

Aftermarket HID to LED Headlight Swap Steps

There are a few reasons why you might want to swap out your HID headlights for LED headlights. For one thing, they’re more efficient and last longer than halogen lights, which means you’ll save on your next oil change if that’s something that concerns you. Here are the steps to swap Aftermarket HID to LED Headlight – 

  1. Remove the headlight by unscrewing the four screws that hold it in place and pulling it out.
  2. Detach the wires by gently pulling them away from the bulb.
  3. Unplug the HID light from the wiring harness by removing the two plugs on either end of the light.
  4. Connect the new LED light to the wiring harness by replacing the plugs and ensuring that they are securely attached.
  5. Replace the headlight by re-installing it on its mounting bracket and screwing it in place.
  6. Reconnect the wires by routing them through the appropriate holes in the chassis and around to their respective plugs.
  7. Replace the screws that hold the headlight in place and re-attach the housing cover.
  8. Recheck all of your work and make any adjustments as necessary.
  9. Test the lights by turning them on and off with the switch on the headlight housing.
  10. Please do not attempt this swap yourself if you are not comfortable working on cars or if you don’t have a set of spare headlights to use in place of your wrecked ones since there is a chance that you could damage your vehicle in the process.

Do You Need A Conversion Kit For LED Headlights?

For the new bulbs to fit properly, a conversion kit is necessary. A conversion kit is a set of brackets and etched diffusers that retrofit your standard halogen headlight housings with the proper cutouts and design to accommodate H4 bulbs.

The plug-and-play conversion kits are easy to install, inexpensive, and allow you to upgrade the lighting in your car without breaking the bank.

Which Is More Brighter HID Or LED?

Which Is More Brighter HID Or LED?

HID bulbs are much brighter than LED bulbs. This is because the human eye perceives much fewer lumens from LEDs than from HID bulbs.

For example, a 12-watt LED bulb would emit about 300 lumens, whereas a 30-watt HID bulb can emit up to 3,000.

LEDs have progressed rapidly over the past few years and are now quite bright. But they are not as bright or energy efficient as metal halide or high-intensity discharge (HID) bulbs.

LEDs are a solid-state lighting source. This means they don’t have a filament or gas inside them as incandescent bulbs do.

LEDs consist of a compact semiconductor chip that is mounted on one end of a tiny circuit board. They are designed to produce light when current passes through them.

Questions For Your Interest

1. How do I change my LED HID to factory?

Changing your LED HID bulb to factory mode is a simple procedure that can be performed by following these steps:

  1. Disconnect the power supply from the headlight using the screws on either side of the socket.
  2. Push down on both sides of the light shield until it snaps out, then pull it away from the headlight.
  3. Unscrew and remove each of the three bulbs in turn – they should all be similar in shape and size (you will end up with a Phillips screwdriver). Note which color corresponds to which element on your car’s wiring diagram (usually red for Ignitor, green for Driver Side Headlamp, blue for Passenger Side Headlamp).

2. Can you replace HID bulbs with regular bulbs?

No, you can’t replace HID bulbs with regular bulbs. This is because HID lights are not just one type of light bulb; they’re a family.

There are specific types of HID lights for different purposes. For example, the HPS lamps used in the greenhouse in your backyard or indoor gardening require a lot more heat than the lights you find at your local grocery store.


LEDs waste far less energy and produce far less heat. They also last between 25,000 and 50,000 hours. That means they can last for eight to ten years at full power.

This is especially important when it comes to security lights, which are just as important as your main transformer in many manufacturing facilities.

The benefits don’t stop there. The replacement of HID lights with LEDs will save your business money on energy and maintenance costs. After reading this article, I hope you know everything about factory HID to LED conversion.
