Buy HELLA 1BL 158 060-021 headlight insert – low beam ECE approved | £95.99
Buy this HELLA 1BL 158 060-021 insert headlight to restore low beam function. ECE approved for right-hand traffic. Professional installation recommended.
The HELLA 1BL 158 060-021 is a low beam headlight insert for commercial vehicles. Unlike a complete headlight housing, this insert contains only the low beam optics and reflector. It fits into a larger headlight assembly. When the low beam reflector degrades or cracks, buying this HELLA insert restores proper light output without replacing the entire headlight unit.
Signs You Need a Replacement Headlight Insert
Poor low beam output
The headlight lights up but the beam pattern is dim, patchy, or uneven. The reflector surface may appear dull, discoloured, or flaking. This cannot be fixed by changing the bulb. A new HELLA insert is required.
Failed headlight inspection
Commercial vehicles require ECE approved lighting. If the low beam fails inspection due to beam pattern or light output, this HELLA insert is a direct replacement.
Physical damage
Cracks from stone chips, broken mounting tabs, or moisture ingress inside the lens. Once moisture enters, the reflector degrades rapidly.
Technical Explanation
How a headlight insert works
A headlight insert contains three main components:
Reflector – Shapes the light into a legal beam pattern
Lens – Protects the reflector and further shapes the beam
Bulb holder – Positions the bulb at the focal point
The HELLA 1BL 158 060-021 is specifically for low beam only (single light function). It is ECE approved for right-hand traffic countries.
ECE approval and traffic direction
This insert is for right-hand traffic (driving on the right side of the road). The beam pattern dips to the right to illuminate the roadside without dazzling oncoming drivers.
Important: This is for left-hand drive vehicles. For right-hand drive vehicles (UK), a different insert is required.
For more information on ECE lighting regulations, refer to HELLA technical lighting documentation.

FAQs for HELLA 1BL 158 060-021 insert headlight
Q: Will this fit my UK right-hand drive vehicle?
No. This insert is for right-hand traffic (Europe, North America). UK vehicles need a left-hand traffic insert.
Q: Why do I need a qualified person to install this?
The headlight assembly must be opened and resealed. Incorrect sealing causes moisture ingress and failed inspections.
Q: Is this a complete headlight assembly?
No. This is only the low beam insert. It fits inside a larger headlight housing.
Q: Can I replace just one side?
Technically yes, but HELLA recommends replacing in pairs for even light output.
Q: What is the warranty on this HELLA insert?
HELLA typically provides 24 months. Keep your receipt.
Q: Does this include the bulb?
No. Bulb sold separately. This is the reflector and lens assembly only.
