There is a 2 pin connector on the under dash fuse boxes side for the dome light. LT BLU & PNK are the 2 wire colors.... one of those is +12V.
The issue with that is the power sockets are switched with the ignition*, as such the light would only have power when the ignition is set to run. The power used by the dome lights is already fused, conversely the Honda Options connector is another source of power - if you installed either the factor fogs, or factor ambient kit you have a plug, its just a matter of tying into it (in the case of the fogs) or adding a new pin (in the case of the ambient kit)#.I am going to tie the glove box light into the 12V socket.
Yellow is fine, it's better than what I have now (nothing), LOL.One thing I noticed was that a lot of the light is covered up by the plastic from the dash. It still lights up the glove box but doesn't seem ideal. I also put a LED light in that I had left over from when I replaced the trunk bulb. I bet it gives you twice the light and the light is actually white instead of that gross yellow.
