Box CV additional front signal light?

[monterey1962]

Years back, didn't someone over on CVN add an extra socket and bulb to the "dead" lens on a box CV? Looks like it'd be fairly easy to do ... drill a hole, pop a socket in there, and hook it to the flasher signal wire.

That being said, are there any issues with doing this? Can a socket fit in there? Looks like a tight space. Also, which would be better ... #194 socket/bulb or a #906/#912 socket/bulb? All input is appreciated, as I am deathly tired and my notes are starting to get blurry.

The same thought had crossed my mind in the past; after all, it's there, it seems as if it should be lit. You'd have to find a socket that mounts with something other than a bayonet mount (talking about the socket itself, not the way the bulb mounts in the socket) since it's difficult to cut the hole the right shape for that, but other than that it seems like a fairly simple project.

The #912 sockets for my F-150's top brake light/cargo bed lights are rubber. They just push into the holes. I figure that would be best to seal from moisture, too.

Oh yeah, push your rubber in the hole!

Wait.

Crap, came out wrong again...

Hi Monterey1962

Adding another turn signal bulb may send the flasher unit nuts unless you use a relay.

Relay should be configered:

Pin 86 - From turn signal flasher relay
Pin 85 - Ground
Pin 30 - Fused power supply
Pin 87 - To your extra turn signal bulb

Alternatively you could fit an uprated flasher relay if one is available.

I've been wondering about two lenses that don't seem to do anything...it's supposed to be like that? neat.

Is this an 88 and up only thing?

Do you think a #194 socket would be enough drain to mess up the flasher unit? To be clear, this bulb would be signal only and would not be used as a "lights on" light. Although, a "lights on" option would be interesting to see.

By the looks of it, there is only enough room inside the lens for a #194 bulb. Don't know if I could get a #906/#912 to clear the actual lens. Depending on what info pops up here, I may just have to experiment with one of my extra #194 sockets tapped into the factory wiring and see what happens.

The point of this is to have a signal light on the front corners so other traffic can see when I'm signaling. I love the '88-'91 CV front styling, but the lack of corner signal lights has always bugged me.

What lense is this?

You would probably get away with using a 194 (5watt) but a 906 (9 watt) or 912 (12 watt) may have a noticable effect in speeding up your turn signals assuming you still have an oldschool bi-metal flasher relay.

What about using LED bulbs they pull only a minimal amount of current?

If the additional bulbs screw up the flasher (it'll refuse to flash) just get a heavy duty flasher--same one you'd get if you had to pull a trailer.

I'd go with a 194. Search the wrecking yards for a 90º rubber socket (I *think* the rear tails of some ford pickups use one of those). Lots of vehicles to look in-side marker lights front and rear, tail lights, running lights, etc. Might even find a repair pigtail in the help section.

Dereck, I've considered going to LED's on my CV, just haven't had the money or the ambition to really do it.

Thanks for the info. Will look into the heavy duty flasher, if necessary. The 90 deg. socket is about the only thing that is going to fit in there. Pretty tight space between the bezel and the car.

I'm talking about the '88-'91 CV's, but I don't see why this couldn't be done on a '79-'87.

Here's what I found out today regarding fitment. I had the old amber lenses lying around and popped the lens off of one. This would be sooooo easy to add a socket/bulb if it weren't for one thing ... there is a divider that splits the unit at the color change of the lens. The orange "reflector" part will allow light through. However, I wanted the whole unit to illuminate. I have two options ... (1) cut the divider out and light the whole unit; or ... (2) rig it up somehow with a bulb in the front (clear) section of the lens. I just don't know how the heck I could cut the divider out without destroying the lens interior. With the divider removed, I could easily fit a #912 bulb in there and it would be nice and bright. If it meant running a relay, then so be it.

You could just do the marker flash mod to make the existing marker bulb flash on or off alternately with the blinker.
