★ Replacement bulb for 24-volt electrical systems, suitable for M38 and M38A1 jeeps and for modified vehicles with 24V conversion.
Application
Suitable for jeeps with 24V electrical system. Please note: M38 (1950-1952) and M38A1 (1952-1971) had 24V as standard. CJ-2A originally had 6V — this bulb is only suitable for CJ-2As that have been converted to 24V.
Installation notes
Check before fitting that your vehicle has a 24V system. With 6V or 12V systems the bulb will blow. The BAY15d base has two contact points at different heights — ensure correct positioning in the socket.
Compatibility
NOT compatible with original 6V CJ-2A, MB or GPW without conversion. NOT compatible with 12V systems. Only for 24V installations as standard on M38 and M38A1, or for vehicles converted to 24V.
Historical context
The M38 and M38A1 were the first Willys military jeeps with a waterproof 24-volt electrical system, introduced in 1950 to increase reliability under harsh conditions.
