I installed small purple neon lights on my first car, 2006 Civic EX Coupe!
I don't really want to put that on my dash so I installed it at the corner (Can't see the light bulb)
It's not really bright but it's bright enough with white reciepts in it.
At the side dash on the driver's side(under the steering wheel), there's a little space for wire cleaning.
(Got this used purple neon lights with bass senser for $10 )
