When in daytime running mode they switch to low brightness and when on blinker at full brightness then back to daytime mode. Very bright. I have regular bulbs in back so not sure if using rear led bulbs would cause these to hyperflash. Install was fast and easy on my car others may differ. ## Frequently Bought Together - Auxbeam B21 Series 3157 Switchback LED Bulbs Built in Resistor CANBUS Error Free Anti Hyper Flash T25 3057 3457 4157 Bulbs White and Amber 600% Super Bright Turn Signal Light DRL Parking Light - Auxbeam T25 3156 3157 LED Bulbs, 6500K White, Super Bright 4114 3057 4157 3457 4057 LED Backup Reverse Lights for Cars Trucks Motorcycles, 3030-SMD 12V, Pack of 2 - Auxbeam H10 9140 9145 Fog Lights, 10000LM 600% Brighter H10 9040 9045 Fog Light, 6500K White Strong Light Penetration, Super Bright Plug and Play --- ## Why Shop on Desertcart? - 🛒 **Trusted by 1.3+ Million Shoppers** — Serving international shoppers since 2016 - 🌍 **Shop Globally** — Access 737+ million products across 21 categories - 💰 **No Hidden Fees** — All customs, duties, and taxes included in the price - 🔄 **15-Day Free Returns** — Hassle-free returns (30 days for PRO members) - 🔒 **Secure Payments** — Trusted payment options with buyer protection - ⭐ **TrustPilot Rated 4.5/5** — Based on 8,000+ happy customer reviews **Shop now:** [https://www.desertcart.gr/products/566900773-auxbeam-b21-series-3157-switchback-led-bulbs-built-in-resistor](https://www.desertcart.gr/products/566900773-auxbeam-b21-series-3157-switchback-led-bulbs-built-in-resistor) --- *Product available on Desertcart Greece* *Store origin: GR* *Last updated: 2026-07-16*
