I ordered a replacement 9 SMD LED (BA9S) for my engine bay light thinking it would give more light than the bulb Im using now. Only problem is the LED won't fit under the standard lens. Its too short. To get it to fit I made a 10mm longer lens out of two other ones I made and from that I made a mold for a new longer lens. Now the LED fits and the end result looks like the original all be it a little longer. Its a lot brighter than my old bulb and uses a lot less current. Im happy. Cha
