lpg system on a p38 4.0 v8

can anybody help,my p38 lpg system when on lpg is burning 1 green light on lpg side and burning 1 green light on petrol side the lights dont flash just burn constant, is this normal,it done this just after i filled with gas yesterday, seems to run ok,:doh: ps its an egas system multipoint?:doh::doh:

the lights only flash when you first start it as there letting you know when its reached temperature when you have 4 green lights flashing drop the revs and it should go solid light and then the 4 lights act as a fuel gauge for the lpg this how my e gas system worked if you contact e gas they will email you a copy of instructions for fre and were very helpfull when i spoke to them hth
