Interior LED Lighting Upgrades - 1967-68 Mercury Cougar XR-7 

Hopefully some of those things were various women haha

We don't have a video for the 67 Standard specifically, but it is basically the same as the 68 XR7, and we do have a video for that: secure.cougarpartscatalog.com/How-To/Dash-Pad-Removal-and-Restoration

Totally understandable, not everyone likes the "cool white" look. We were just talking about this. They do make most of these same LED bulbs in "warm white" color temperature, which looks more natural but is still brighter. We may try to source these and make both options available.

My 67 std with the lighter aqua interior really POPPED when we put in these icy blue bright lights. The video may not show it but they do have a slight blue hue to the 1156. As I get older I just cannot see as well with no dome light, especially on the dark colored interiors. It is also nice that you can leave your doors open for 3 hours and not kill your battery. A must for your trunk light whether you like the color or not.

Putting LED's in shouldn't make the ALT light come on - you likely have something else going on, like an alternator that's about to fail.

The diffusers are located inside of the instrument cluster and diffuse the light as well as tint the light color. They are available in blue (oem color), yellow or red: secure.cougarpartscatalog.com/store/Search.aspx?SearchTerms=panel%20diffuser&CatID=0. They are only held in by one screw, so once you have the cluster opened up, they are not difficult to replace, but you may or may not need to replace them depending on the condition of your originals. Here is a pic of where they are located inside of the 70 cougar cluster: secure.cougarpartscatalog.com/17924/32036/housing-instrument-cluster-used-1970-mercury-cougar.html

Just when the lights are on and I chose not to do that one as it seems bright enough

would it be the same bulb as door courtesy lights, clock, etc? I'd like to make my shifter display light brighter. I've thought about wiring to be on with key on. But I can just drive with my running/marker lights on and achieve the same thing.

The shift indicator light uses a 1445 bulb, inside a metal shroud that focuses the light. We haven't tried putting an LED in there, but don't think it would fit because of the shroud. If you find out otherwise, let us know!

Good question! Yes they are.

Yes!

It's true that LED's draw less power, but each one doesn't need its own relay. Usually what happens when you change all your turn signal bulbs to LED is, the factory flasher relay will "hyperflash" as if a bulb is out, because it isn't getting the amount of current it expects. So in most cases you only need to modify or replace the flasher relay to be compatible with LED's. Cougars are a little more complicated because of the sequential turn signal system.

Nope, he's still not done with it...

You dont like lower power consumption and long service life?
