• 700% Brighter: Each Phinlion 1157 switchback LED bulb features 5 high power & super bright multi-die CSP LED chips with 360° light output. Delivering 4200lm high output per pair, it boosts visibility by 700% over stock halogen bulbs for safer, clearer illumination in rain, fog, snow and night‑driving conditions
• CANBUS Error Free Design. Built-in resistor and smart IC driver, Canbus-ready and compatible with 99% of vehicle systems. No error warning, no hyper flash, and no extra resistor required. Simple 5‑minute plug‑and‑play installation. A small number of vehicles may still encounter CAN‑bus compatibility issues such as no white/amber light, non‑operation, hyper‑flash. External load resistors may be required to fix the issue, please reach out to us via Amazon Buyer‑Seller Messages for support and solutions
• Dual Color & Dual Function: White for parking light/daytime running driving light; Amber yellow for turn signal light. The turn signal flashes "amber-off-amber-off" instead of "amber-white-amber-white", delivering better visibility to surrounding drivers
• Triple Heat Dissipation. Phinlion 1157 LED switchback turn signal bulbs adopt full aviation aluminum body, copper substrate PCB and 12,000RPM silent cooling fan. This three‑layer heavy‑duty thermal solution effectively draws heat away from LED chips, preventing premature light decay and burnout, supporting an extended service life up to 50,000 hours
• Note: These 1157/2057 switchback LED bulbs only work with dual contact bulbs that combine parking light and turn signal light in a single bulb. Fit Bulb Sizes: 1157, 1157A, 1157NA, 2057, 2057A, 2057NA, 2357, 2357A, 2357NA, 2397, 3496, 7528, 1016, 1034, BAY15D, P21/5W and other equivalent bulb models
