How to install updated Spyder taillights?

Spyders usually only have one turn/park fixture on each corner. Some guys wire the "city lights" in the headlight bucket as park bulbs either alone or with the smaller front lights. I didn't.

The clear ones in front use amber bulbs, park and turn. I used a 3157 amber LED with appropriate socket. If you use LED lights you can easily change to an LED flasher. I found a 2 wire(yours may be 3) model by Audew on Amazon for 6 bucks.

The rear light assemblies use the same bulb but clear. I got the bulbs right at Autozone.

There are two ways to tackle the wiring. Most guys use a trailer converter, the kind that you use to wire a european tow vehicle to the single taillights on a trailer. 5 wires in, 4 wires out: blue=stop, yellow=left turn, green=right turn, brown=park, and white=ground. There are 4 wires out, the same colors all, excepting the blue. Easy peasy. If you go this way, buy a good one, they used to have a tendency to burn out. I believe this tendency may be alleviated by using LED bulbs, as they draw less current.

I did it another way. I used 4 relays for the turn/stop function. Two relays are wired to the brake switch and rear bulbs and the other two relays to the front turn bulbs. If you search VW turn signal wiring you can find schematics.

Either way you do it, I recommend you include a 4-wire trailer pigtail near the clamshell hinges for easy on-off. I've been doing it this way for twenty years and it works very well.

I'm sure there are other ways to do it.

In some countries they REQUIRE 2 separate fixtures for the taillights, and usually the stop lights are red and the turn signals are amber. Easy to do with a Speedster, either the beehives or the teardrop lights have provision for separate bulbs. Not so in a Spyder.

Danny has you covered.  We do most with the trailer box as he mentioned.  Something like this: https://www.amazon.com/56130-N...tive%2C87&sr=1-4

One quick tip, in case the little note wasn't put in with the lights, The 3 tabs on the lens and the 3 mounting bolt heads (that hold the base to the car) make a triangle.  Make sure you install the lens with the triangle of tabs opposite of the triangle of bolt heads, otherwise the bolt heads can hot the tabs as it "clicks" together and break them off.  Hope that makes sense.

Thanks for the tips! I had no idea that trailer module was a thing or I would have probably headed in that direction! I bit the bullet and just drilled a couple of holes in the buckets and replicated the existing setup since I was already on my knees and coved in fiberglass dust over the weekend. LOL... Works as expected and definitely looks better than the cone lights that were there!
