Electrical Parts Return-Prevention Note

1. Match the complete SKU 144352/B.
2. Confirm the motorcycle is one of the catalogue-matched retired Bullet configurations.
3. Do not order for Electra 4S / 5S simply because the motorcycle is an old 350.
4. Do not order for UCE or J-Series motorcycles.
5. Compare connector count, connector shape and harness routing before opening / fitting.
6. Modified motorcycles with aftermarket tail lamps or indicators require extra verification.

Correctly supplied electrical parts are not returnable or exchangeable because of incorrect model selection, connector mismatch, modified wiring, mechanic recommendation, incorrect diagnosis or change of mind. Eligible wrong-item or damaged-item claims require applicable proof and a complete unboxing video under store policy.

Competitor Gap Analysis

Most seller listings simply call 144352 a “Bullet 350/500 tail light wiring harness,” which is too broad. The official Royal Enfield retired-model matrix is more precise: 144352/B is marked for Bullet 350 Standard, Deluxe, Machismo, Campus and Bullet 500, while Electra 4S/5S and later lean-burn/Thunderbird applications use different rear-light harness families. This listing preserves that model-level distinction to reduce wrong electrical-part orders.
