★ Reliable halogen headlamp bulb for converted 12 volt systems. Suitable for vehicles converted from 6 volt to 12 volt electrical installation.

Application

Suitable for vehicles with 12 volt electrical system. Many post-war military jeeps were originally equipped with 6 volt (CJ-2A 1946-49, CJ-3A 1949-53, CJ-3B 1953-64) or 24 volt (M38 1950-52) systems and were later converted to 12 volt for improved performance and parts availability.

Installation notes

Do not touch the glass of the bulb with bare hands — use gloves or a clean cloth to avoid fingerprints which shorten service life. Verify that your electrical system has been correctly converted to 12 volts before installing this bulb. Always replace headlamp bulbs in pairs for symmetrical light output.

Compatibility

NOT suitable for original 6 volt systems — only for vehicles converted to 12 volts. The M38 with original 24 volt system requires complete electrical conversion. Standard P45t fitting fits in original headlamp holders without modifications.

Historical context

From the 1960s onwards, many owners began converting their 6 volt jeeps to 12 volt for better starting power, brighter lighting and easier parts availability. The P45t H4 bulb became the standard for these conversions.
