Upgrading your Vw Jetta Mk3’s headlights can significantly improve visibility and driving safety. This article guides you through installing German-made In-Pro projector headlights, covering necessary adapters, bulbs, and common questions.
Understanding the In-Pro Projector Headlights for VW Jetta MK3
In-Pro headlights are known for their quality and performance. While information on these specific German-made projectors for the MK3 Jetta may be scarce, this guide will help you navigate the installation process. We’ll address common concerns and provide practical advice for a successful upgrade.
Required Adapters for In-Pro Headlights on a VW Jetta MK3
European-spec headlights (often called “E-codes”) utilize a different wiring configuration than US-spec headlights. Your VW Jetta MK3 likely requires a 3-pin to 4-pin adapter to connect the In-Pro headlights to the car’s wiring harness. This adapter ensures proper functionality of the low and high beams. The adapter linked in the original question (https://www.ebay.com/itm/2923900939…dvLQbFfnCy5YM+RM3PITNic1Tn|tkp:Bk9SR9DlhJX1YA) appears to be a suitable 3-pin to 4-pin adapter for this purpose.

Alternatively, using a pigtail adapter (https://www.ebay.com/itm/134183077846?hash=item1f3def47d6:g:yW8AAOSwQv5i4QRp&amdata=enc:AQAHAAAA4LgxZDSYsJEQRP8Avgkg1P8mvrgnn3jSSLCQHsaI5AMyf9RaFRzIUgF2r/lOLaF03+jeVqkc4+S+10tc1BUy0Pr1wvcTh5+jXzjqi56kESvjirjnKXnpqBiFeYpCjOGBqr/wl/dcr+LKnCnYvmGQIsvtSbbqnrS+jYX8VDtak5V46ATQFjp440CkIjoT+UUXq6a0RAesq5pr8b0WA0ol0xgxraGjGX8h7D9GZU/1pjt8FVkY26UgycnyB4L86oY7EHrn+dyOHB+jSCE5NLCsCgaiQKHGB2NmsJtAm+cWEKZX|tkp:Bk9SR_rmk5T1YA) like the one linked could also be a viable option. This would involve splicing into the existing wiring.
Bulbs for In-Pro VW Jetta MK3 Headlights
The yellow sticker on the headlights indicating “H7” likely refers to the bulb type. H7 bulbs are a common type used in many vehicles. You will need two H7 bulbs per headlight, one for low beam and one for high beam. Confirm that the In-Pro headlights do not come with bulbs pre-installed before ordering.
Conclusion: Successfully Upgrading your VW Jetta MK3 Headlights
Upgrading your VW Jetta MK3 with In-Pro projector headlights offers potential improvements in lighting performance. Ensure you have the correct 3-pin to 4-pin adapter and the necessary H7 bulbs. While these specific headlights might not be widely documented, understanding basic wiring principles and bulb types will facilitate a successful installation. Remember to consult your vehicle’s wiring diagram for precise guidance.
