Tech Expert HID Headlight Ballasts

Tech Expert's OE-Exact-Match HID Headlight Ballasts are direct-replacement parts that match the fit, form, and function of the originals to help restore proper lighting function to HID light systems. Plus, as DOT-certified parts, Tech Expert's HID Headlight Ballasts comply with Federal Motor Vehicle Safety Standards.


Tech Expert High Temperature Headlight Harnesses

The heat generated by modern OE automotive light bulbs can melt the bulb’s connectors. To prevent melting, Tech Expert's Headlight Wiring Harnesses have high-temp connectors that can withstand extreme heat. The harnesses also have 14-gauge wire for better conductivity and a “plug & play” feature that lets you plug the harness right between the factory harness and new bulb. You can even use the harness as a pigtail if the original connector is melted. Tech Expert’s line of headlight harnesses covers the following high-temp bulbs: H1, H3, H4, H7, H11, 9004, 9005, 9006, 9006XS, and 9007.

Tech Expert VW / Audi Cam Follower

Tech Expert offers a high-quality direct replacement Cam Follower for 2013-06 VW/Audi 2.0T.

This can lead to extreme engine damage and an expensive repair.
