Royal Enfield Thunderbird 350 & 500 Complete Headlamp Assembly with Bulbs – 594029/C
Restore the original twin-lamp front lighting arrangement of the compatible Royal Enfield Thunderbird with this genuine complete headlamp assembly. The current manufacturer reference is 594029/C, replacing the earlier catalogue number 594029/A.
The original Thunderbird parts catalogue identifies this item as Head Lamp Assembly with Bulb and shows one assembly for both Thunderbird 350 and Thunderbird 500. The assembly uses two separate H7 12V 55W bulbs in the original configuration.
Critical fitment warning: this is for the original-generation Thunderbird headlamp arrangement. Do not order it for Thunderbird X, Meteor, Hunter, Classic, Bullet or another Royal Enfield merely because the lamp looks similar. Confirm the old part number, connector arrangement, mounting system and VIN-specific catalogue before opening the package.

Pre-Purchase Fitment Checklist
- Confirm the motorcycle is the original-generation Thunderbird 350 or Thunderbird 500.
- Check that the old assembly is 594029/A or that the current VIN catalogue specifies 594029/C.
- Compare the complete lamp shape and twin-lamp arrangement.
- Match all electrical connectors, wire colours and pin positions.
- Match the mounting points, grommets, bolt spacing and housing clearance.
- Confirm that the motorcycle has not been converted to Thunderbird X or universal lighting.
- Inspect the product photographs and package label before ordering.
Installation Notes
- Installation should be completed by a qualified motorcycle electrician or Royal Enfield technician.
- Disconnect the battery according to the workshop procedure before handling lighting wiring.
- Compare the new and removed assemblies before plugging in or making mounting marks.
- Do not cut wires, change connectors or drill mounting points to force compatibility.
- Confirm correct high beam, low beam, beam aim and warning-light operation after installation.
- Use only the specified bulb rating; an incorrect wattage can overheat wiring or housings.
- Never touch bulb glass with bare fingers.
- Set headlamp aim according to local regulations before riding at night.

Yes. The current /C reference is listed as the replacement for the earlier 594029/A assembly.
3. Is this a complete headlight?
Yes. It is the complete headlamp assembly rather than only the chrome rim, housing or internal lens unit.
4. Are bulbs included?
The factory description states “with bulb,” and the original assembly uses two H7 12V 55W bulbs. Confirm the sealed package contents before installation.
5. How many bulbs does the original assembly use?
Two H7 12V 55W bulbs are shown for the original Thunderbird headlamp arrangement.
6. Does it fit Thunderbird 350?
Yes, for the original headlamp application when the old or VIN-specific reference matches 594029/A or 594029/C.
7. Does it fit Thunderbird 500?
Yes, subject to the same exact-reference, connector and mounting confirmation.
8. Does it fit Thunderbird X?
No fitment is claimed for Thunderbird X. Its lighting style and application must not be confused with this assembly.
9. Is this only for BSIII models?
It is commonly catalogued for the older Thunderbird application, including 2013–2017 BSIII listings. Confirm by VIN rather than registration year alone.
10. Will it fit a BSIV Thunderbird?
Only if the VIN-specific Royal Enfield catalogue explicitly specifies 594029/C.
11. Does it fit Classic or Bullet models?
No compatibility is claimed for Classic, Bullet or Electra models.

No. The motorcycle’s main wiring harness is separate.
13. Is the chrome rim supplied?
This is identified as a complete assembly, but buyers should verify the exact visible package contents in the product photographs.
14. Can I buy only the internal lamp unit?
Older catalogues list separate internal-unit references, including 594579/A and 594580/A. Those are different products.
15. Can I install LED bulbs instead?
No LED conversion compatibility is promised. Use only a setup approved for the exact housing, wiring and local regulations.
16. Can I splice the connector if it differs?
No. A connector mismatch indicates that fitment has not been confirmed. Do not modify the assembly to force installation.

No. Correctly supplied electrical components are not returnable after opening, plugging in, testing or installation.
18. Who should install and align it?
A qualified motorcycle electrician or Royal Enfield technician should install it and set the beam aim.

Provide a continuous unboxing video, package labels, clear photographs and original packaging within 24 hours of delivery.
