How many to change a Fiat light bulb....socket?

Post by njoconnor »

Two people, actually...and it helps if one has a jeweler's pliers.... :)

I've mentioned my non-working taillight issue in other posts. With literally everything else in the light circuit working (minus hazards...still poking at that), I decided to tackle the remaining taillight. With great offline tutoring and help from David L, I'd managed to narrow the issue to a non-functional socket. I still had both old, scarfed up taillight fixtures, so I had possible replacement parts. Figured I'd post a few pix of the changeout process for anyone interested.

First, I tested one of the potential replacement sockets (still in its housing), with the yellow power lead and a jumper ground. Worked great! Using a drill and 11/64 bit, I drilled out the rivets, and had this:

Shined up all the contacts and the inside of the socket with the Dremel tool, and moved on to the surgical candidate:

Again, drilled out the rivets with the 11/64 bit. Once disassembled, the problem with the faulty socket was clear: bad corrosion/rust on the positive side of the socket; the difference is clear in this picture:

Image

Off to the local True Value hardware, and had two choices to refasten the socket: rivets and little tiny screws.

Image

I couldn't set up a secure way to crush the rivets, between all the plastic of the housing and the recessed locations of the fasteners, so I went with the screws...and threadlock!

Image

The fastener towards the bottom of the picture (in the u" shaped recess) caused the most hassle. I was struggling to fit the nut on the srew while holding the screw head with the #0 Phillips, when Pat (spouse) walked up and said "My jeweler's pliers would fix that." So with her smaller fingers and that pliers, we had the screw threaded and fastened down securely. Off to the rear of the car, insert the LED bulb, hook up all the power/ground leads, and flip the switch:

Image

Tail lights! On both sides!! :D Ran checks on the other circuits, and everything still works. Time for a Spotted Cow on the gazebo! (Trunk prop by Home Depot).

Hope this helps someone else with a non-functional bulb socket. It's a fidgety repair, and that second pair of hands is needed, but worth the effort.

Bonus pic:

Image

After supper (and a couple of Cows), went back out to the garage and finished trimming out the gauge openings on the new soft dash (fuel gauge bracket wasn't clearing the dash opening). Trimmed it out with the Dremel and a zip (side cutting) bit. Messy...have a shop vac handy. But it came out looking good, and.... :shock: ....all the gauges lit up with their new LEDs AND worked when I started the engine! On to the console!

nice work. i had taillight issues as well. fortunately, fixing it wasn't as involved as yours. as plenty of others have said, clean up the connections! it works wonders.

Excellent addition! I'm wondering...when I re-install the aluminum fasteners, would coating the insides with some spray NoCo cut down on the galvanic reaction?

Are you familiar with pop rivits? Or, is your application to small of a diameter?

I wanted to use pop rivets (have a bunch), but I could not find a size small enough to fit the openings. IIRC, I ended up using something like a #2 or #3 machine screw/nut combo. I did find regular compression rivets, but like I said, could not fashion a solid and safe (for the fixture) anvil/striking method to crush the rivet tails.

This works, and if I come across a better method, easily reversed. But, yeah, pop riveting would have been easier and faster if the right size was available.

I just used Neil's post on tail light repair to replace a faulty socket and worked great. This post was spot on!

My sockets rotted out internally and the standard universal push in metal sockets at the local auto parts store worked just fine. Installation was a breeze since they just pushed into the lamp housings. I just crimped insulated male spades on the wires and all is well.
