Disco 2 Work / spot lights

Hello all , I'm wanting to fit some small 7x2 rectangular LED lights . 2 on the grill and 2 on rear on corners of the roof by the door above the gutter .

Is there any gutter brackets on the market ? Also what's best way to feed cable in from the rear . Not keen getting trapped in the door shuts .

And mounting options for on grill be great also.

Cheers
