These are the non-polarity ones, I needed these bulbs for the idiot lights and the turn signal indicator and they worked perfect. Just installed them, can’t speak to the bulb life. Included a couple pics of the fuel gauge, incandescent vs LED. ### ⭐⭐⭐⭐ Non dimming *by M***B on August 1, 2024* They work well, pretty bright which was what I wanted. They don't dim which may bother some buyers. ## Frequently Bought Together - Ruiandsion BA7S Instrument LED Light F3 1 LED 12V DC Blue Car Mini Bulbs Lamps Led Car Instrument Light Warning lamp,Negative Earth (Pack of 4) - Antline BA9S BA9 1895 1891 53 57 47830 64111 3893 LED Bulb Amber Yellow, Super Bright Canbus Error Free 12 Volt Replacements for Interior Dome Map Lamp License Plate Glove Box Lights (Pack of 10) - Ruiandsion BA9S LED Bulb BA9 1895 1891 53 57 Warm White 6V LED Bulb 3030 2SMD Chipsets LED Replacement Bulbs for Car Interior Dome Map License Plate Glove Box Lights (Pack of 4) --- ## 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.us/products/198440023-ba7s-instrument-led-light-f3-1-led-12v-dc-blue](https://www.desertcart.us/products/198440023-ba7s-instrument-led-light-f3-1-led-12v-dc-blue) --- *Product available on Desertcart United States of America* *Store origin: US* *Last updated: 2026-08-27*
