I have read alot of posts about what you guys do when you show up to a site, so most people use cones and I also heard about strobe lights , the hide- away type, I Will be using my truck for 90% personal use so this sounds like a good option for me. I also think they are pretty cool. Do you recommend having four bulbs ,one in each corner , or having six two in front, and four in the back? also what should I do about my trailer? how can I put lights on that ? I am thinking that I can run a strobe off a battery in my tounge box , or is there a way to tie it into the wiring? any pics? thanks in advance!
