- Adhere to all local and national regulations regarding vehicle lighting.
3. Package Contents
Upon opening the package, please verify that all components are present and undamaged:
- One (1) Pair of Tail Lights (Left and Right)

4. Installation Instructions
These Winjet Street Series LED Tail Lights are designed for direct fitment into the factory location of your 1999-2005 Volkswagen Golf GTI MK4, requiring no modifications. However, professional installation is recommended.
Required Tools:
- Basic hand tools (e.g., screwdriver set, socket wrench set)
- Wire strippers/crimpers (if resistors require wiring)
- Electrical tape or heat shrink tubing
Installation Steps:
- Preparation: Park the vehicle on a level surface and engage the parking brake. Turn off the ignition and disconnect the negative terminal of the vehicle's battery to prevent electrical shorts.
- Access Old Tail Lights: Open the trunk or tailgate. Locate the access panels or retaining screws for the existing tail light assemblies. Remove any covers or fasteners to gain access to the back of the tail light.
- Remove Old Tail Lights: Disconnect the electrical connectors from the old tail light bulbs/assembly. Carefully unbolt or unclip the old tail light assembly from the vehicle body. Gently pull the assembly straight out to avoid damaging paint or bodywork.
- Prepare New Tail Lights: Inspect the new Winjet LED Tail Lights. Ensure the included volt resistors are properly connected or prepared for connection according to the vehicle's wiring system, if necessary.
- Install New Tail Lights: Connect the electrical connectors from the vehicle's wiring harness to the new Winjet LED Tail Light assembly. Ensure a snug and secure connection. If resistors are separate, connect them as per vehicle requirements to prevent hyper-flashing or error codes.
- Mount New Tail Lights: Carefully position the new tail light assembly into the vehicle's opening. Align the mounting points and secure the assembly with the factory bolts or clips. Do not overtighten.
- Repeat for Other Side: Follow steps 2-6 for the opposite tail light assembly.
- Test Functionality: Reconnect the vehicle's battery. Turn on the ignition (do not start the engine) and test all tail light functions: running lights, brake lights, turn signals (left and right), and reverse lights. Ensure all lights illuminate correctly and without error messages.
- Final Check: Once confirmed operational, ensure all wiring is neatly tucked away and secured. Replace any access panels or covers.

5. Operating Instructions
Once properly installed, your Winjet Street Series LED Tail Lights will operate automatically with your vehicle's existing lighting system. They are designed to function as direct replacements for your factory tail lights.
- Running Lights: These will illuminate when your vehicle's headlights or parking lights are turned on.
- Brake Lights: These will illuminate brighter when the brake pedal is pressed.
- Turn Signals: The amber section of the tail light will flash when the turn signal lever is activated.
- Reverse Lights: The white section will illuminate when the vehicle is shifted into reverse gear.
Regularly check all lighting functions to ensure they are working correctly for safe driving.
6. Maintenance
Winjet LED Tail Lights are designed for durability and minimal maintenance. Follow these guidelines to ensure their longevity and optimal performance:
- Cleaning: Clean the lens with a soft cloth and mild automotive soap and water. Avoid abrasive cleaners or harsh chemicals that could damage the polycarbonate lens material.
- Inspection: Periodically inspect the tail light assemblies for any signs of damage, cracks, or moisture intrusion. Ensure all mounting bolts remain secure.
- Wiring: Check wiring connections periodically for corrosion or looseness, especially after driving through harsh conditions.
- Weather Sealing: The lights feature weather sealing to prevent moisture. If you notice condensation inside the housing, inspect the seals for damage.
7. Troubleshooting
If you encounter issues with your Winjet LED Tail Lights, refer to the following common problems and solutions:
| Problem | Possible Cause | Solution |
|---|---|---|
| Lights not illuminating | Loose electrical connection, blown fuse, incorrect wiring. | Check all wiring connections. Inspect vehicle's fuse box for blown fuses. Verify wiring against vehicle's electrical diagram. |
| Lights flickering or dim | Poor electrical connection, insufficient power, faulty resistor. | Ensure connections are tight. Check vehicle's voltage. Inspect or replace volt resistors if suspected faulty. |
| Hyper-flashing turn signals | Resistor not properly installed or faulty, vehicle's computer detecting low load. | Verify volt resistors are correctly installed and functioning. Consult a professional if the issue persists. |
| Moisture inside lens | Compromised weather seal, extreme temperature changes. | Small amounts of condensation may dissipate. If persistent or excessive, inspect seals for damage. Contact support if seals are faulty. |
If these steps do not resolve the issue, please contact Winjet customer support.
