DIY: High Intensity Discharge (HID) headlight installation

Abstract
This thread documents a do-it yourself (DIY) guide for the installation of high intensity discharge (HID) headlights on a 2007 Toyota Camry Hybrid using a HID kit. This guide should apply to all current generation (6) Toyota Camry Hybrids and possibly all other models (such as CE, LE, and XLE).

Overview of converting to HID headlights
There are various ways to convert a vehicle with halogen headlights to HID headlights. The most common method is to use what is called a "HID kit." HID kits are sold by a number of on-line retailers and at various price points. HID kits are also sold by many detailing and after market automotive parts dealers and installation establishments.

An alternative method for HID headlight installation is to perform a retrofit. This method results in the most accurate installation and an installation that does not pose a glare annoyance to oncoming vehicles. Retrofitting is usually more expensive and time consuming.

There are also various color temperatures of HID bulbs. HID bulbs typically range from 3000K to 12000K. The lower the color rating, more yellow the emitted light. The higher the color rating, more blue or purple the emitted light. The most visible light output is at around 4300K. For more information on HID bulb color temperature, see the following (courtesy of Mobile HID):

The advantages of HID headlights are:

• More visible light (lumens)
• Lower operating power (wattage)
• Longer life span (hours)

If you are unfamiliar with the term "high intensity discharge" in relation to automotive headlights, the following is suggested reading:

• [Wikipedia] High-intensity discharge lamp
• [Wikipedia] Headlamp: HID (xenon) light sources

Time required for installation
The amount of time required for installation of a HID kit depends on your level of expertise and whether or not you use a wiring harness or are able to use a wiring adapter keeping the stock wiring.

The following times are estimates for planning purposes only:

Beginner: 5 hours
Intermediate: 3 hours
Experienced: 1.5 hours

Tips for a successful installation

1. Read all installation instructions.
2. When using a wiring harness, make sure you locate the fuse and relay in a location that will not allow them to get wet. If the fuse or relay get wet, the functionality of your system will be compromised.
3. Be very mindful of keeping the parts of your kit dry and out of direct contact with water.
4. Use caution when removing the left and right splash guard (engine undercover) support pins under the vehicle. The middle of the pin pops out allowing you to remove the entire pin. If you force the removal, the pin teeth will break. These pins are about $2 (USD) each.
5. Take your time.
6. Do not be afraid to innovate and be creative. The method described in this guide is just one of the many ways to install and HID kit.

Required tools and supplies
The following tools are required to use this guide.

• HID kit - H11 plugs (see note 4)
• Ramps or jack stands
• Philips head screwdriver
• Socket wrench (ratchet)
• 10mm and 12mm socket
• Needle nose pliers
• Drill (see note 2)
• 3/8" or 1/2" drill bit (see note 2)
• 3/4" galvanized pipe strap, about 6 inches - two 3 inch pieces (see note 1)
• Felt or pipe insulating tape (see note 3)
• Electrical tape
• Zip ties
• Time
• Patience

Notes:

1. The galvanized pipe strap was used because it was on hand from a previous plumbing project. The pipe strap was also used because it provided a stiff mounting support and the ability to mount using existing bolts (the ballasts used mounting hardware that was too small to mount to an existing location). Other mounting methods could be used (such as velcro, zip ties, and so on).
2. The use of a drill depends on the type of galvanized pipe strap you use. Due to the size of the bolts used for mounting, a hole in the pipe strap must be enlarged.
3. The felt or pipe insulating tape was used to pad the back of the ballast to reduce possible damage to the ballast during installation and from the pipe strap.
4. This guide uses the Mobile HID 5000K digital ballast HID kit. If you purchased a different kit, you should be able to follow the same basic instructions.
5. When using a digital ballast you have the option to power the ballast directly from the stock wiring. When using the Mobile HID digital ballast kit, you will require Mobile HID to supply you with a modified harness to connect the stock H11 plug to the ballast plug.
6. For safety reasons, this guide will instruct you to power the HID headlights by way of their own power source and use the stock wiring to trip a relay as opposed to powering the HID headlights directly. This does not require any additional harness parts when using the Mobile HID kit.

What's in the box
When you purchase a HID kit you will usually receive the following items:

• Two ballasts (digital or non-digital)
• Two HID bulbs
• Wiring harness

Hello everyone,

I recently completed the do-it-your guide to HID headlight installation.

I did my best to write it up in a way that would work for the least to most experienced individuals. I also relied on my memory and if I made any mistakes, please let me know. Specifically, I am not 100% sure of the socket sizes and was not 100% sure about the number of push pins (some of mine were missing).

Finally, it took me much longer to write this up than it did to do the actual installation. Using the wiring harness adds about 30 minutes to the total time - give or take. If you use the stock wiring adapter, this guide will take you longer to read than to do the actual install.

Good luck.

I hope this is of help to someone!
Mike

 

This is awesome. This guide is of such high quality that I am now considering an HID upgrade for my TCH. I'll definitely be checking back often for updates.

Thank you so much for doing this!

 

What he said!

 

Thanks Andrew and Ed. I will hopefully have it done soon. There is not much left to write.

 

Hello everyone....its done. (I think)

 

Thanks Mikie. Awesome guide...now to scrounge up a few extra dollars...haha
