I did a little surfing the other night and found a couple of different sleepy eye modifications. One of the mods I found allows you to use a momentary switch that you can use to raise your highlights to any height you desire and keep your headlights turned off.
The mod also allows you to operate your headlights normally when you want and you don't have to do any physical damage to your car to install it! So if it doesn't work or you decide you don't like it or dont want it anymore, you can simply remove it and replace the retra fuse.
