Xenon HID (High-Intensity Discharge) Low Beam Bulb Install – 5th Gen 4Runner
The Xenon Depot HID bulbs are a pretty simple install. Because Xenon Depot includes the 3M adhesive backing on their ballasts, it makes the install go much smoother as opposed to some other HID installs.
With the other HID ballasts, you need to drill a hole into your firewall and then thread out that hole. With the XD HIDs, you don’t need to worry about this. Just peel back the 3M and place your ballasts on the firewall where you see fit.

The point of all our installs is to hit the end and make you say “damn, I feel like I just did that install”. We hope that this step by step guide on HIDs will do that.
Where can you get these bulbs?

Step #1 – Preparing your HIDs
Step #2 – Cutting Plastic from Shipping Housing
Your lights come in a protective housing. You will need to cut the protective housing off. You can split these off with your fingers but its much easier with a pair tapered nose cutting pliers.
Step #3 – Cutting Plastic Shipping Ring
Also, cut off the base of the protective housing with your tapered nose pliers.
Step #4 – Adjusting Blue Seal Ring to Bottom
The bulb seals come positioned just below the tabs. You need to move the seal ring to the bottom-most position of the bulbs for proper fitment before installing.
Step #5 – Connecting HID Wiring
Start connecting up all your wiring.
Step #6 – HID Wiring Connected and Ready
Step #7 – Connecting HIDs to OEM Harness
Connect your HIDs to your OEM outlet and always test your bulbs before fulling installing.
Step #8 – Testing HID Bulbs
Step #9A – Drill 1″ Hole in Dust Caps
Yes, you need to drill your dust caps for this one. Try to be as precise as possible about this to prevent gaps between your rubber grommet and the dust cap. If you drill too wide, you will end up having moisture build-up in your headlight housing. This creates a whole new problem and topic so get it done right the first time.
Step #9B – Feed HID Wiring Harness Through Dust Caps
Step #10 – Plug in your HID Bulb
Plug in your bulbs, twist the bulbs into place and then lock down your dust caps.
Step #11 – Marking a spot for your Ballasts
Step #12 – Peeling back your 3M and Preparing your Ballasts
Step #13 – Attach your Ballasts to Firewall
Passenger Side Step #14 – Optional Drill Hole in Weather Stripping
Step #14 – Ziptie Ballast Wiring Through Weather Stripping
Step #15 – Ziptie Loose Wiring and you are done!
Factory Halogen Low Beams
Both of these pictures were taken on different days. I tried to get them as close as possible but my headlights have changed a few times and I have not had factory bulbs in for some time.

Note: This is after I adjusted the headlights. We adjusted the lights at a height of 25″ off the ground where the cutoff line is from 25′ away from a wall.
