Very cool very easy IMO.
The goal here is to add running lights to ur bumper lights for that extra posing action.

Step one. Drill hole in bumper light housing. I used a 7\16 drill bit. A 5\8s MAY work better. I had to hog it out quite a bit.

 

Step two. Buy urself 2 194 sockets. These are generic chrysler license light sockets off the shelf of oreillys. Others are available. U are then gonna extend set wires that lead off socket. Only need about 6-10 in. Of extra wire depending on how u route it

 

Slowly make the hole larger till the socket pops in snugg. I recommend putting the bulb in socket before setting in housing as it kind of pinches the bulb making iy snugg yet difficult to get in after the fact...

More to come in a second I got busy at work! Please no postes before im done! Thank you!

 

Next ur gonna wire the new socket to the corner light harness. I like this spot cause the harness is small and is easy to replace if u go back to stock and dont want connectors gunking things up. Now all 4 wires are power. Power goes in one side of bulb and out the other so no worries in crossing wires. Either wire from new socket to either wire on corner light harness. Soldering and heat shrink recommended. Solderless connectors and electrical tape at ur own risk!... there are fancier ways to hook this up more "factory ways" so this methods at your own risk entirely. Im comfortable with it and have had no ill effects on past vehicals.

 

Delete me please!

 

This is ur finished product. And the blinkers bulbs being bigger put out more light than the 194s so blinkers are still very apparent.
Obviously for best results replace all 194s in vehical with the awsome ones fromom superbrightleds.com

This same design also works for adding city lights to your headlights after replacing ur glass sealed beam headlights to a plastic non sealed housing.
Thanks for reading. Hope this helps someone. Though simple some less experienced members may find it useful to see it before doing it.
I am now done

 

Definitely be doing this in my truck

 

just needs the wire from the parking light wired in.
not shown, my switchback 194's on my corners.

 

I like ^ LEDs are a fantastic mod and cheap I'm just waiting for someone to stuff an hid light in there they run pretty cool but don't no if the plastic can take it ... Not to mention the blinding light even on 3k

 

my LED's are plenty bright. You can get my LED's in a larger/ taller size with more LED's on it if you wish.
the HID's would take a while to warm up and then the flashing part is where it'll lack in. LED's are more practical and effective, and won't melt your housings
All you need to do is add a 3-wire socket. mine's a 1157, similar to the truck's 1156, but another contact in the socket.



similar idea to what the OP has, but in LED fashion without the drilling.

 

yea the hids would definetly melt the lense/housing.

 

That's kinda wat I was refering to when I mentioned other fancier ways to do it . The 194 socket s were left over from a job I had finished prior for a customer. So it was a FREE mod. My fav kind
