Well I've been bottom bulb racing since I started back in 2000. First it was footbrake with a turbo350, then 4 yrs ago I went to a glide with transbrake still bottom bulbin. So I finally decided to try a delay box so I pulled the trigger and bought a "little wizard". Just installed it today. I set it up with a quick disconnect plug so the box can b removed and a jumper wire so when I want to bottom bulb i can. up here u have to remove the box from the car if ur running anything else than super pro or "top e.t" Haven't tried it yet so I have no idea if I'm gonna even like top bulb racing but I won't know unless I try. Lol
