my new footwell neons
I did this between classes today. From the looks of these products in stores, you'd think they'd be very tacky. In my opinion, if done right, a cool blue light can be tasteful. These are 9" cold cathodes on each side held up with adhesive and hardwired in to the back of the cigarette lighter and hooked up to a stock-looking switch.
I also added a DRL/auto on disable switch while I was at it to the same switch panel.
