Features
- 12 volt rating
- Dual filament: 21W (brake light) and 5W (tail light)
- BAY15D bayonet fitting with offset pins
- Suitable for combined brake/tail light assemblies
- Standard for 12V conversions
★ Essential component for any 12-volt conversion project. The dual filament ensures correct operation of both tail and brake light functions.
Application
This bulb is intended for vehicles converted from the original 6V or 24V system to 12V. During a 12-volt conversion, all bulbs, including this tail light bulb, must be replaced with 12V versions.
Installation notes
Pay attention to correct orientation of the BAY15D fitting — the offset pins ensure proper placement. After installation, test that both the tail light function (5W) and brake light function (21W) operate correctly.
Compatibility
Only suitable for 12-volt systems. Do not use in original 6V military systems or 24V M38/M38A1 systems without conversion. When converting from 6V to 12V, all bulbs, the dynamo/alternator, voltage regulator and starter motor must be adapted.
Historical context
During conversions of military jeeps to 12-volt, this type of dual-filament bulb became standard to maintain modern functionality whilst allowing original tail light assemblies to be reused.
