Review on DS18 Headlight Bulbs All Conversion by Michael Nard

[UPDATE May 2019] Less than 5 months later these LEDs were vibrating. As you can see from the photo, in this short time the gasket was deformed, which allowed the LED to move. The gasket itself is made of softer silicone than other flashlights I've tried. There is NO way to get this back through Revain. It's a good price at $50 for a pair. However, the headlights are a bit loose in the body. However, with all the extra cords and transformers that need to be plugged into the back of the case, this should keep the bulb from coming loose.
