Installing Hella 500s Behind the Grill
The Dodge Ram 5.7L HEMI© has a good amount of room between the radiators
and the grill. It also has two very conveniently located cross members which
make a great mounting point for behind the grill off-road lighting. This is a
pretty easy mod, and the Hella 500 lighting kit I received has very nicely
done installation instructions. I ended up wiring mine a bit different though
because I wanted it to be a completely independent setup. The downside to
having it completely independent is that I could forget to turn them off and
kill the battery overnight.
One thing you have to remember about doing behind the grill lighting is that
the grill design (especially the 2005 PW honeycomb design) isn't conducive to
flood or fog lighting because it doesn't allow much lateral light escape. This
means the lights you choose need to be driving lights / pencil or spot beams.
I didn't have a big enough deepwell socket to get the lights torqued down
properly so the alignment is off. Once I get the right socket, I will not have
both lights converging exactly on the same spot, but maybe a couple to four
feet apart. The lights were also pointed down a little, so I need to raise
them a bit.
For two 55w lights, they do pretty good. Getting on a back road with no traffic
it really lights the distance up quite a bit.

Same, but no flash
Got the ground (blue) and relay power
Nice long wires for easy routing and install
Wiring done, they're on
Low-beams and Hellas on single point
Lights off with hood closed
With the hood opened
Low-beams, fogs, Hellas on (with flash)
High-beams and Hellas on single point
Drilled two holes 12" from centerline
Probably the only time these lights will have covers
Head on (some alignment) no fogs
Using the hood latch to center from
A little black Rustoleum paint
Here's the grill before
Head on no fogs
Temporarily wired switch
LED lights up when on
Here's what's in the kit
Another angle with them on
Quick check to make sure they're even
No LED light when off

Hi, I am wanting to get my husband the same kit for his 2004 Dodge Ram. Do you know if the Hella 500 would work for his truck? Also, have you been happy with the Hella 500s or should I look at another brand? Any other information I should know about fog lights behind the grille?

I followed your same directions and added two lights behind the grill on my dodge ram just like you did. But the lights I bought didn't come with any wiring or anything. I want to wire the lights with a switch. Now I know absolutely nothing about wiring yet because im still young. Could you help me figure out how to wire my lights to a switch please??

Looks cool! I'm in the process of building a woven mesh grille to replace the existing grille on my Sprinter 4X4 to mount the lights behind. It will let out more light than the factory setup and will hinge down for cleaning the lenses and changing bulbs etc.
Does the back of the lamps get too hot? Have you noticed the bulbs burning up too quickly?
