Have been looking at lightbars and couldn't find the one I wanted. My disco has factory fit roofbars and I wanted something to sit between them and be low profile.
I found some rectangular Ring lamps which fitted the bill size-wise and so started scrounging and a customer agreed to bend the steel for the bar for me.
The bar itself has a kink to push it forward of the front sunroof, so that (a) it still works and (b) there's no light entering the vehicle from above. It attaches to the two roof bars forward of the first cross-bar. The lamps are held therefore on the roof line, far enough back so that the roof line stops bonnet reflections and far enough forward to be of some use ;) Lights are 2 x spots centrally and 2 x fogs outboard all with 55W bulbs.
The four lamps are wired to a junction box on the bar itself, so that I only had to run 2 wires down the driver's door pillar and then to the usual fuse/relay/isolator switch combination for auxiliary lights.
Total cost a tenner for the junction box, a fiver for the steel bar, thirty quid for the lamps and another fiver or so for connectors, switches and relay.
The only thing I will be chaging soon is the junction box, got this one from Vehicle Wiring Products, but it's large and has a glass lid which is not ideal. I need to scan around for a smaller torpedo-shaped one which is weatherproof to tidy it up a bit.
All in all as my first bodge I'm quite pleased :) Sample photo here, more in my gallery.
