Review on Alla Lighting DE3021 DE3175 LED Bulbs: Super Bright 4014 10-SMD 28mm 29mm 12V LED DE3022 6428 Bulbs for Festoon Interior Map, Dome, Trunk, Door Lights - 6000K Xenon White by Ronnie Saylor

Revainrating 5 out of 5

29mm is the right size for the 2020 Subaru Outback dome light

Fits the 2020 Outback Limited XT better than the 31mm bulbs which Revain says are standard. Since incandescent bulbs have a flange, Revain says a 31mm bulb will fit. But LED lamps do not have flanges, so lamps with a diameter of 31 mm bend the contacts too much. These 29mm bulbs are snug, but not too tight.

Pros
  • Sturdy construction
Cons
  • Not bad
