An 880 bulb is a 27-watt single-filament capless bulb on a PG13 base, used for fog lamps, spot lamps, and daytime running lamps. The 880 is an H27W/1 bulb, and its close relative the 881 is an H27W/2 bulb on a PGJ13 base, so the two share the 27-watt filament but differ in base. The bulb pushes and locks into a fog or spot lamp on cars, 4x4s, tractors, and plant machinery where the lamp needs a bright, single output. Knowing the 880 and 881 by their 27-watt rating and their PG13 or PGJ13 base answers the question behind most 880 searches.
This guide explains what an 880 bulb is, how the PG13 and PGJ13 bases differ, why 880 and 881 name two bulbs in one family, what the bulbs are used for, how they compare with the H3, and how to replace one with halogen or LED.
What an 880 (H27W) Bulb Is
An 880 bulb is a bright halogen bulb with one filament on a capless plastic base. The number 880 is the trade code, H27W is the technical name, the 27 gives the 27-watt rating, and the single filament gives one output level, so the 880 suits fog, spot, and driving duties that need a strong single beam. The 880 is the H27W/1 version, and factors print both the 880 code and the H27W/1 name on the box.
The 880 produces a bright, focused output from a compact capless bulb. The 12V 880 runs 27 watts, the plastic PG13 base locks into a matching holder, and the single filament switches full on or off, so the 880 lights a fog lamp or a spot lamp that needs a clear, single beam. The lamp reflector, not the bulb, shapes the final beam on an 880.
The PG13 and PGJ13 Bases
The 880 uses a PG13 base and the 881 uses a PGJ13 base, both flat plastic capless bases about 13 millimetres across. PG marks the plastic prefocus family, the J on the PGJ13 marks a keying tab that the plain PG13 lacks, and the number 13 gives the base width in millimetres. The base clicks into the lamp holder and holds the filament at a set focal point, which keeps the beam aimed.
The base keying is the detail that sets the two apart. An 880 (PG13) has a plain base with no locating tab, while an 881 (PGJ13) has a base with an extra keying tab, so an 881 fits an 880 holder but an 880 can sit loose in an 881 holder that expects the tab. A buyer checks whether the lamp holder has the keying slot before choosing between the 880 and the 881. The capless wedge bulbs used elsewhere are covered in vehicle bulb types explained.
880 vs 881: One Family, Two Bases
The 880 and the 881 share the 27-watt H27W filament but differ in base. The 880 is the H27W/1 on a plain PG13 base, and the 881 is the H27W/2 on a keyed PGJ13 base, so the two are one bulb family split by base rather than by output. The table below sets out the split.
| Bulb | Technical name | Base | Wattage | Keying |
|---|---|---|---|---|
| 880 | H27W/1 | PG13 | 27W | Plain, no tab |
| 881 | H27W/2 | PGJ13 | 27W | Keyed tab |
The base is the difference. An 880 fits a plain fog-lamp holder, while an 881 fits a holder with a keying slot, so the two are not always interchangeable even though both run the same 27-watt filament and both suit fog and spot lamps. A lamp built for the plain base takes the 880, and a lamp built for the keyed base takes the 881. Both carry the same colour temperature and the same beam potential, so the choice comes down to the holder.
What an 880 or 881 Bulb Is Used For
An 880 or 881 bulb fills a bright, single-function auxiliary lamp. The 27-watt filament suits four common roles, listed below, which is why the H27W appears across cars, 4x4s, and working vehicles.
- Front fog lamps on cars, vans, and light commercials.
- Spot and driving lamps on 4x4s, tractors, and plant machinery.
- Daytime running lamps on vehicles that use a dedicated DRL housing.
- Auxiliary forward lamps on off-road and agricultural machines.
The fog and spot role defines the bulb. A 4×4 or a tractor runs an 880 or 881 in a fog or spot lamp, so a vehicle with an H27W auxiliary housing carries the 880 or the 881 to match the holder. The fog role across lamp types is covered in fog lamps explained, and the spot and driving role in driving and spot lamps explained.
880/881 vs H3: Which Fog and Spot Bulb
The 880, the 881, and the H3 all light fog and spot lamps, but they use different bases and mounting. The 880 and 881 use a flat plastic PG13 or PGJ13 base that clicks in, while the H3 uses a small PK22s base with a flying lead, so the lamp housing decides which bulb fits. The output is similar, and the base is the deciding factor.
An 880 or 881 suits a lamp with a click-in plastic holder, common on modern fog housings and many LED-ready spot lamps. An H3 suits an older or a traditional spot and fog lamp with a wire-lead base, common on classic driving lamps and some agricultural work lamps. A buyer reads the existing bulb code before ordering, because an H3 lamp will not take an 880 and an 880 lamp will not take an H3. The wire-lead fog and spot bulb is covered in H3 fog and spot bulbs explained.
LED 880 and 881 Conversions
An LED 880 or 881 replaces a halogen bulb in the same PG13 or PGJ13 holder, and the fog and spot role drives strong upgrade interest on 4×4 and plant. The LED bulb keeps the plastic base, clicks into the existing holder, draws less current than the 27-watt halogen, and gives a brighter, whiter fog or spot light with a heat sink or fan to manage the higher output. The upgrade suits off-road and yard use where the extra brightness helps.
An LED 880 or 881 in a road fog lamp needs care over the beam and the approval. The fog and spot role uses a reflector tuned to a halogen filament, so an LED that sits its emitters off the filament position can scatter light and dazzle other drivers, which fails the beam pattern a road fog lamp needs. A road vehicle uses an E-marked LED fog bulb that places its emitters at the halogen focal point, while an off-road spot lamp on a tractor or a 4×4 takes an LED 880 freely for yard and field work. The wider retrofit rules sit in LED headlamp conversions.
How to Replace an 880 or 881 Bulb
Replace an 880 or 881 bulb by reaching the lamp, unclipping the capless bulb, and fitting the matching code. Five steps cover the job on most fog and spot lamps, so work through them in order.
- Reach the fog or spot lamp from behind, through the wheel arch or under the bumper, and unplug the wiring connector.
- Release the bulb by pressing its retaining clip or twisting the holder, depending on the lamp.
- Pull the old 880 or 881 straight out of the holder by its plastic base.
- Choose a replacement of the correct code (880 for a plain PG13 holder, 881 for a keyed PGJ13 holder), in halogen or an E-marked LED for road use.
- Line the base up with the holder, push the new bulb in until it clicks or locks, reconnect the wiring, and test the lamp.
Handle the new bulb by its plastic base to keep the glass clean, because the H27W is a halogen bulb and a fingerprint can shorten its life. Confirm the base matches the holder before pushing the bulb home, since an 880 and an 881 look alike but key differently. For 880 and 881 bulbs in halogen and LED, see the bulb range.

Summary
An 880 bulb is a 27-watt single-filament capless bulb on a plain PG13 base, and the 881 is the same 27-watt bulb on a keyed PGJ13 base. The 880 is the H27W/1 and the 881 is the H27W/2, both used for fog lamps, spot lamps, driving lamps, and daytime running lamps on cars, 4x4s, tractors, and plant. They differ from each other only in base keying, and from the H3 in base type and mounting. Match the code to the holder, fit an E-marked LED for road fog lamps, and click the base fully home.
