Review on DE3175 Festoon LED Car Bulb, 31mm 1.22in, Super Bright White, Pack of 6pcs - Ideal for Interior Map, Door, and Dome Lights - Fit for DE3021 DE3022 LED Car Bulb by Chris Long

Our battery died because the kids left the courtesy light on AGAIN. So I decided it was time to replace it with LEDs. Searching the web told me I needed this "DE3021" style lamp for my 2005 pilot. I later discovered that only 2 out of 14 interior lights use the DE3021 style. So if you are looking for interior bulbs for a 2005 Honda Pilot you will need the following: 6641: 4x for visor/cosmetic lighting DE3021: 2x for tailgate578: 4x for handle lighting 194: 4x - 2 for front map lighting and 2 to illuminate door panels at foot level . Also note that the "578" wasn't big enough in diameter to fit directly onto the handrail lights, but it's a fuse mount so it worked. It is enough to just clamp the attachment points to "reduce" them sufficiently. For the tailgate seats, this product was ideal. It just doesn't fit between the contacts and works fine.
