HELLA H1 Inner Headlight Conversion Kit 510/1600 & More - Pair

Convert your Datsun's factory sealed-beam high beams to replaceable H1 globes with this HELLA Semi-Sealed High Beam Conversion Kit. Supplied as a pair, these 146mm round inserts retain a classic fluted-glass appearance while allowing the globes to be replaced separately from the housings.

Primarily offered for the Datsun 510/1600, this kit also suits other Datsun models using the same 146mm round high-beam headlights. Choose No Globes, Philips H1 +30 halogen globes or J.W. Speaker H1 LED globes. These inserts replace the inner high-beam-only lights and complement the outer H4 high/low beam conversion kit.
