Description
Overview:
The Bulb 12v 21w Bau155 Amber 'E' - Pack Of 10 - 400 179 is a set of bayonet-fit signal bulbs for plant, agricultural and garden equipment running 12-volt systems. Each lamp uses a 21-watt filament to produce a bright amber output that stands out in daylight and low light for clear signalling. The glass envelope and metal bayonet base provide a dependable, serviceable construction suited to equipment that sees vibration and regular use. These lamps are a straightforward swap for tired or failed indicator and warning light bulbs on machinery such as excavators, dumpers, ride-on mowers and compact tractors. Supplied as a cost-effective pack of ten to keep on hand for routine maintenance and quick replacements (reference 400 179).
Key Features:
- 12V, 21W amber lamp for clear signalling on machinery
- Bayonet base for quick push-and-twist fitting and secure contact
- Consistent light output to support visibility and site safety
- Durable glass and metal construction suited to vibration-prone equipment
- Direct replacement for existing amber warning/indicator bulbs (Bau155 type)
- Supplied in a pack of 10 to minimise downtime and cover multiple fittings
- Suitable for beacons, indicators, hazard and marker lamps on 12V systems
- Reliable performance with standard wiring and holders used on plant and garden machinery
- Practical stock item for workshops, service vans and site spares kits
- Helps maintain compliance with site visibility practices where amber signalling is required
Typical Applications:
Used in indicator and warning lights on construction machines, ride-on and commercial mowers, compact tractors, UTVs, small trailers and site equipment. Ideal for cab-mounted signal pods, fender indicators, light bars with 12V bayonet holders, and general amber signalling where a 21W filament bulb is specified. Suitable for routine servicing, pre-season checks and quick field repairs to restore safe, visible signalling.
