### ⭐⭐⭐⭐ Worked once adjusted.
*by K***N on 11 September 2025*

At first it did not seem like these were compatible. I bought them for spares to replace the halogen reading lamps in our motorhome. The one I tried failed to light at the first attempt. However, I bent the contacts slightly to improve the connection and, hey presto! A good, bright, soft yellow light. The pack of 6 should last us years.
