HY21W Canbus 3 SMD Amber LED Indicator Bulbs For Audi Volvo Peugeot
The HY21W BAW9S Amber LED indicator bulbs upgrade side markers, turn signals, and parking lights with immediate, high-efficiency illumination. Each unit houses three OSRAM 3838 SMD chips driven at 2.9 watts, delivering 150 lumens of bright yellow light that projects 360 degrees around an anodized aluminum heatsink. The integrated Canbus driver eliminates hyper-flashing on modern European vehicles, keeping your dashboard warnings off while replacing aging halogen filaments.
Compatible with Audi, Volvo, Peugeot, and other models using HY21W or BAW9S sockets, this 12–22 V DC design operates reliably across a broad temperature range of -40°C to +90°C. Rated IP65 waterproof, the sealed metal construction resists road spray, corrosion, and vibration. With a documented service life reaching 50,000 hours, you gain consistent visibility without recurring part replacements.
Benefits & Tips
- Direct swap installation: Pop out the original glass bulb and insert the LED into the factory housing—no extra wiring, resistors, or ECU coding required.
- All-season durability: The IP65 enclosure and thermal management aluminum keep internal components cool and dry, maintaining brightness through rain, snow, or salty coastal roads.
- Orient for optimal reflection: Install with the LED panel facing the center of your reflector cup so the 360-degree output feeds directly back onto the road.

Warnings & Reminders
Confirm your vehicle’s stock bulb uses the HY21W or BAW9S fitting before purchasing, as physical footprint variations exist between manufacturers. Clean socket contacts and dry light cavities prior to installation to prevent premature failure. Avoid contacting the SMD chips with bare skin, as natural oils can insulate the board and reduce Heat sink efficiency.
