I bought set of puddle lights recently, not the cheap eBay 3w LED imports from China but some high quality units, complete with 7w CREE bulbs and fitted with twin-coloured Dodge projected logos.
The lights were intended to fit in the bottom of the doors and shine on the floor when the door opens. The problem is, getting wiring from the door to side the car is nearly impossible (thanks, Dodge).
So I spent a while looking for an alternative use for the lights and came up with the idea of replacing the original white bulb footwell lights and so a plan was formed!
Tucked up under here:
Is a hole though which a light shines when you open the door.
Removing the lining reveals the bulb itself, with a domed diffuser.
Removing the lower dash panel reveals just two wires going to the back of the bulb (+12v and GND).
The bulb assembly is held in place with just the one screw and here’s how it looks when removed.
I debated removing the bulb from this holder and drilling out the centre but that seemed a bit over the top so I decided to make a bracket to hold the new LED lights.
First of all I made a cardboard template (well, I made a couple) and got everything in the right place and nicely lined up.
And from the top:
Here was another version, same idea, just slightly different alignments.
Once happy with the cardboard template, it was time to transfer it to something more permanent.
Grabbing the nearest Tupperware box from the kitchen the plastic was nice and thick, perfect for holding the lens unit.
For some reason I forgot to take photos of the next steps, but it was a simple matter of placing the cardboard template over the plastic and drawing around it, then cutting it out.
Once the plastic bracket was ready it was simply screwed in place of the old lamp assembly.
The end result is that now when you open a door on the car, there’s a coloured DODGE logo projected on to the floor mats.
And on same thing on the drivers side.
It’s really hard taking photos in low light.
I bought four of these originally, one for each door – not sure what to do with the remaining two now.
I’ll let you know if I come up with an idea for the remaining two 😎
