How bright and durable are the ROADEAL assemblies?

Each lens uses high-transmittance polycarbonate with a UV protective coating to keep clarity and resist yellowing. The BMC reflector material tolerates very high temperatures and reflects more light than common reflectors, improving visible output without modifying electrical load.

• BMC reflector rated to withstand up to 570°F for stable reflection
• Approximately 20% greater brightness compared with many standard materials
• UV-coated PC lens for long-term clarity
• Includes HB4 (9006) low beam and HB3 (9005) high beam bulbs; turn signal bulbs not included

Are these headlights weatherproof and easy to install?

The housings meet an IP65 ingress-resistance level to block dust and low-pressure water jets, helping prevent condensation and water damage in wet or snowy conditions. Installation is straightforward: they swap in for the stock assemblies with plug-and-play connectors and require no cutting or drilling.

• IP65-rated sealing prevents moisture intrusion and dust entry
• Direct replacement with factory-style plugs and mounting points
• No modifications, drilling, or extra wiring required for standard models listed
• Works in cold, rainy, and windy environments without performance loss
