Headlight Lens & H4 Bulb Kit | Honda CB175 / CB200 / CB350 / CB450

The factory sealed-beam headlight on these vintage Hondas is dim, and when it burns out you replace the whole unit. This 6.25″ lens converts your headlight to a modern, replaceable H4 bulb, so you get a brighter beam and never throw away the lens again.

Why You Need This

A fifty-year-old sealed beam goes dim and yellow, and you can’t just change the bulb, because the bulb and lens are one sealed piece. This lens drops into your factory bucket and trim ring and takes a standard H4 bulb you can swap anytime.

The kit comes with a 35-watt H4 halogen, a real step up from the old sealed beam while staying within what these old charging systems can handle. Want more light with even less draw? Choose the LED bulb at checkout.

Specifications

Note: Stick with the 35-watt bulb. A common 55- or 60-watt H4 is too much load for these old charging systems.

Note: This lens mounts differently from the factory sealed beam and bypasses the left-right aim screw, so you aim it by tilting the bucket. That’s normal, not missing hardware.

Model-Specific Notes

• CB360 / CL360: These use a 6.25″ lens, but it won’t seat in the CB360 / CL360 factory bucket. Use our Headlight Bucket & H4 Bulb Kit instead. The CJ360 does take this lens.
• CB450 K5–K7, CB500T, CB550: These use the larger 7″ headlight. See our 7″ Halogen Headlight Lens & Bulb Kit.

What’s in the Kit

• 6.25″ H4 conversion lens (marked “top” for orientation)
• H4 bulb (35W / 35W halogen, or LED if selected)
• Mounting hardware
• New electrical pigtail connector

Note: The headlight bucket and trim ring are not included. This is a lens-and-bulb kit that drops into your existing bucket.

Installation

Difficulty: Beginner

Tools needed: Screwdriver, needle-nose pliers

1. Remove the trim ring and take out the old sealed beam.
2. Seat the new lens in the trim ring with the “top” mark up. It’s held by wire clips, and needle-nose pliers help on the first install.
3. Wire the included pigtail into your headlight harness.
4. For the optional yellow parking light, connect the green wire to ground and the brown wire to the parking-light power at the gauge cluster.
5. Reinstall the trim ring and aim the light by tilting the bucket.
