How we checked
CORRECTED FROM SEED (fitment): direct guesses at a dedicated SL1 catalog URL 404'd — Diode Dynamics' current headlight-bulb lineup is built around SL2/SL2 Pro — but the legacy SL1 pair listing itself is still live via on-site search as a discontinued clearance item, confirming it was only ever sold in H9/9005/9006 fitments and never in H11 (the seed category's baseline fitment). Page confirms 6000K cool white, 9-16V input, -40C to 85C operating range, active cooling via Sunon microfan + copper core board + zinc casting, boost-mode driver circuit with current-monitoring, 20-30 min install time, $80.00 clearance (was $199.95), 30-day warranty only (discontinued/non-returnable). Lumens, wattage, and rated lifespan hours are not published on the surviving page, so left blank.
