EiKO A-3625 6V 25/25W BA20d Heavy Duty Motorcycle Scooter Headlight Bulbs Pair

Description

Up for sale is a brand new, new-old-stock (NOS) EiKO Heavy Duty Auto Bulbs Twin Pack, part number A-3625. This premium dual-filament replacement lighting kit features heavy-duty filament architecture engineered specifically to absorb constant chassis thumping and road vibrations without burning out premature.
Featuring a vintage BA20d round base layout (Bosch style) with dual contacts on the bottom, these bulbs run on a vintage-correct 6-Volt electrical current. They deliver separate, precise high-beam and low-beam functions while drawing a safe 25 Watts to prevent delicate classic wiring harnesses and magneto charging coils from overloading. They come sealed as a pair inside their original retail card stock blister packaging.

  • Brand: EiKO (Heavy Duty Automotive Series)
  • Part Number: A-3625
  • Base Fitment Profile: BA20d (Bosch Style Round Flange Base)

  • Quantity Included: Two (2) Individual Bulbs (Twin-Pack Set)

Vehicle Fitment & Application:
These specialized 6V BA20d bulbs feature direct plug-and-play fitment across an array of classic European and vintage metric lightweight vehicles running on older 6V charging systems:
  • Vintage Scooters: Direct fit for early classic Vespa (such as standard VBB, VNB, Sprint, and Super models), classic Lambretta, and retro Piaggio configurations wired for 6-Volt electrical networks.
  • Classic Mopeds & Minibikes: Fits a wide selection of vintage 1970s and 1980s mopeds, lightweight step-throughs, and classic utility machines from Puch, Tomos, Sachs, and Motobecane.
  • Vintage Motorcycles: Fits smaller-displacement vintage metric street and trail bikes from Honda, Yamaha, Suzuki, and Kawasaki built prior to the industry shift to 12-Volt systems.
