Definitely recommend. ### ⭐⭐⭐⭐⭐ Works as it should for a Tool light. *by B***B on August 13, 2025* So far so good. Nice and bright. ### ⭐⭐⭐⭐ Pfix your Pfaff *by D***A on December 2, 2018* Good replacement for the bayonet base bulb in our Pfaff 7550. Pformance is a little better than stock... some improvement in light brightness and NO HEAT. I have to believe that eliminating the heat from an incandescent bulb, will help prevent the lubricant in the sewing head from gumming up. --- ## 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.tn/products/78256814-led-ba15d-double-contact-bayonet-base-120-volts-4w-led](https://www.desertcart.tn/products/78256814-led-ba15d-double-contact-bayonet-base-120-volts-4w-led) --- *Product available on Desertcart Tunisia* *Store origin: TN* *Last updated: 2026-07-22*
