anyone know how you set up those ram things like on the comp trucks? Ive seen them on a rack of some sort, in a cage that is lowered backwards by the ram, at the flick of a switch inside the cabin!
P.S. i have a GQ LWB

Am still working on my setup, (have been for the past 12 months.... cant rush these things). But am using little Festo air-rams, only coz they were free.
There have been various threads on the subject, though have yet to see someone do a full-on step-by-step instruction guide with all measurements etc. Would be a nice little project to do...
Some US mob (Lightforce USA perhaps? cant recall) were selling complete framed units; can recall seeing a whole unit on a stand at some 4x4 show review article in 4wd monthly mag yonks ago.

Yea, ive been looking at doing this on my ute somehow to, been looking around for a cheaper air ram to do the job, i think the hinge / brackets would be pretty easy to make up.

by 'electric ram' do you perhaps mean "linear actuator"
contact T.E.A transmissions for info or pricing.

On the Little Mule we have set up the roof lights on a hinged rack with gas struts to hold them up. The advantages are that if you hit an overhanging branch or similar the lights fold back and then pop up again as the don't go over centre when they hit something. They're cheap.
The down side is you have to get out to put them up and down. and it's not as bling.

Mate of mine here in Toowoomba just made up one these on his ute using
a 12v ram, or linear actuator, as it's been described. The ram bolts to one
of his roll bars on the tray and he made up pivots to lay the bar back. Will
see if I can get some photos or a write-up about it from him.

I would use a pneumatic cyl or gas strut, instead of an electric actuator. Reason being if you haven't lowered the lights and hit a branch or fallen tree, the electric actuator is more likely to be damaged.
