Before ordering a replacement driving, fog or headlamp bulb, identify more than its glass shape. HELLA's H1, H2, H3 and R2 lamps have different bases and electrical requirements. A bulb that looks similar may not seat correctly or may draw far more power than the original lamp was designed to use.
Four bulb families are not interchangeable
H1 · single-filament halogenHELLA 002089541 uses a P14.5s base and is listed at 12 volts, 55 watts. Confirm the headlamp housing's specified H1 fitment.
H2 · distinct connectorHELLA 002857122 is a 12V 55W H2 bulb with an X511 base. It is not interchangeable with a P14.5s H1 simply because its wattage is also 55W.
H3 · check the wattageHELLA 002090671 is a 12V 130W H3 with a PK22s base. It draws much more power than a common 55W H3; its intended high-wattage application must be checked before use.
R2 · different voltage and baseHELLA 002088255 has a P45t base with a 24V 55/50W dual-filament specification. Do not substitute it for a 12V H1, H2 or H3 lamp.
HELLA MPN, base, voltage and wattage chart
Match the exact manufacturer part number, bulb designation and base code to the existing assembly's specified replacement lamp.
| HELLA MPN | Bulb | Base | Voltage | Power | Lamp type |
|---|---|---|---|---|---|
| 002089541 | H1 | P14.5s | 12V | 55W | Halogen headlight bulb |
| 002857122 | H2 | X511 | 12V | 55W | Driving and fog lamp bulb |
| 002090671 | H3 | PK22s | 12V | 130W | High-wattage driving/fog lamp bulb |
| 002088255 | R2 | P45t | 24V | 55/50W | Dual-filament multi-purpose bulb |
High-wattage H3 warning: 002090671 is a 130W H3 product, not a general substitute for a 55W H3 bulb. Check the HELLA high-wattage/off-road application designation, local road-use rules, the housing's thermal capacity, vehicle wiring and circuit protection. A matching H3 base alone is not enough to make the substitution safe or legal.
What to inspect before installing a replacement
- Read the old bulb's type, voltage and wattage markings or look up the exact original lamp specifications.
- Inspect the socket and retaining mechanism for the specified base: P14.5s, X511, PK22s or P45t.
- Check the vehicle's electrical system. The R2 part on this page is 24V, while the listed H1, H2 and H3 parts are 12V.
- For a fog or driving lamp, check the lamp housing's wattage and heat limits. A 130W H3 should not be installed merely because the socket fits.
- Use the approved lamp type for road use; fitment in a housing alone does not establish street legality.
Common bulb-selection questions
Can I replace an H1 with an H2? No, not without a lamp assembly specifically designed for that bulb. The bases are different even at the same rated power.
Is the 130W H3 a brighter drop-in for any H3 fog light? No. Higher power requires an appropriately rated lamp assembly, wiring and electrical system, and its usage may be restricted.
Is an R2 24V bulb suitable for a 12V vehicle? No. Match the original electrical system's rated voltage and the specified lamp.
Find each HELLA bulb by exact part number
These four catalog listings are separate bulbs. Check each product for current availability, actual item condition and the correct base designation; catalog photographs are for identification, not evidence of the condition of an individual item.
