I made sure them work correctly with turn on engine before put them in headlights units. Brightness is good and nice white and turn to amber then back to white. It takes less than a second for switching color but I don't think it's big problem. My old switch back last long years so I give shot to this.

I use 50W 6ohm load resistor is good for the turn signal light on Black wire and Blue wire and it LOOKS NICE!!! **Q: Which resistors do you recommend because I've read that some are better than others?** A: 50W 6ohm load resistor is good for the turn signal light **Q: Will I need the resistors for a 2014 honda accord?** A: Wiil I need the resistors for a 15 Nissan Altima ? **Q: I bought 2 sets of these and they look like 2 different style bulbs. Are they different or the same?** A: In my experience sometimes you will be sent an older version of the same lightbulb the color may be slightly off or it may not be as bright or it may be brighter. First read any numbers on the light bulbs themselves and match them to the documentation if they are both the same then go ahead and plug one of them in and see if it reacts the same way as the other then you will know for sure. ## Customer Reviews ### ⭐⭐⭐⭐⭐ Give it a shot *by K***T on April 7, 2026* The Alla switch back LED lightbulbs installing were easy and it works good on 2007 Dodge Ram 1500 with aftermarket headlights.

The white is bright like fog lights ### ⭐⭐⭐⭐⭐ Phenomenal, finally a brand that WORKS *by G***R on October 8, 2025* You have no idea how many bulbs I've gone through trying to find working ones that wouldn't hyperflash. These are a+. I was even able to remove the nonsensical giant resistors from my wiring, these bulbs didn't need it and had perfectly working flashing and switches back to white when not turning. ## Frequently Bought Together - Alla Lighting T25 3457 3157 Switchback LED Turn Signal Lights Dual Color 6000K White/Amber Yellow 12V 4157NAK 3457AK 4057 3057 3757AK 5702AK 4157AK Extremely Super Bright 2835 28-SMD Upgrade - Marsauto 194 LED Bulb 6000K White 168 T10 2825 W5W 5SMD Replacement Bulbs for Car Dome Map Door Courtesy Side Marker Reading Glove Box License Plate Lights (Pack of 10) - AUXITO 3157 LED Bulb White, Super Bright 3156 3056 3057 4157 3047 4057 3457 4114 LED Bulb for Backup Reverse Tail Brake DRL Signal Parking Lights, Pack of 2 --- ## 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.sg/products/22141718-alla-lighting-t25-3457-3157-switchback-led-turn-signal-lights](https://www.desertcart.sg/products/22141718-alla-lighting-t25-3457-3157-switchback-led-turn-signal-lights) --- *Product available on Desertcart Singapore* *Store origin: SG* *Last updated: 2026-10-10*
