IAN M8 CAN U PUT THAT LINK ON FOR THEM SIGNSTX JERRY
If you mean putting your own name, logo, or livery, on the trip signs as Ian has done for the Window Washers organisation- but don't have his contacts, then; simply print off whatever you want in full colour, laminate it, and stick it to the sign.
You could get some caution cones from varitec 01626 830 830 they are fairly good about £15.00 all in each they come with cation trip hazard trailing hoses stickers and they are sand wighted so will not blow over and they look the part as well.Oliver Collins
