Yes, this headlight insert is designed for suitability in both right-hand traffic (RHT) and left-hand traffic (LHT) systems.

You must verify that the dimensions (167mm L x 167mm W x 100mm H x 109mm D, 150mm Diameter) and the H4 lamp type match your vehicle's specific requirements. Checking your vehicle's owner's manual or consulting a professional is recommended.

An H4 bulb has two filaments: one for the lower power low beam, used for general driving, and a separate, higher power filament for the brighter high beam, used for increased visibility when there is no oncoming traffic.

Clean the glass lens with a soft, damp cloth. Avoid using abrasive cleaners or scouring pads, as they can scratch the glass surface.

Hella is a leading global supplier to vehicle manufacturers. 'OEM-quality' signifies that the product meets the same high standards for precision, performance, and reliability as parts originally installed by the car manufacturer.

Check the H4 bulb for proper seating and filament integrity. Verify the vehicle's fuse for the headlights is intact. Ensure wiring connections to the insert are secure and free of corrosion.

Confirm the headlight insert is correctly mounted and aligned within the housing. Ensure the H4 bulb is installed in the correct orientation. Check for any debris or damage on the glass lens.

Inspect the seals around the headlight insert and bulb access point for damage or improper seating. If moisture is present, carefully dry the interior and ensure all seals are re-established to prevent further ingress.

Check the electrical connections to the headlight insert for looseness or corrosion. The H4 bulb itself might be faulty or nearing the end of its lifespan.
