Modern Vespa

How easy/difficult would it be to convert these motorcycle spotlights to be a combined Daytime Running Light / Indicator (turn signal) unit - preferably when the indicator is flashing, the DRL would automatically dim/switch off and then back on once the indicator had been cancelled, although this is not a necessary requirement but it'll look good.
Or as an Angel Eye with indicator unit in the centre.
Using LED's so I can connect them straight into the existing GTS indicator connections.

May i ask for what purpose?

A link to whatever 'these' spotlights actually are would be a good idea, so we can tell what's in them.

Attila:
For a 'rat' project I have in mind - I'm thinking of replacing the stock indicator units, welding up the holes and putting a couple of 'spotlights' on the front to replace them.
Think something similar to this..... but with a modern twist.

Jimc:
Just a generic spotlight unit.
I'm more interested in what's required to wire up a combined DRL/Indicator unit to work on a GTS than the 'how do I take these apart" part of the project.

I have never bought a GTV as I feel the headlamp is not visible to car drivers as it is lower than the boot (trunk) lid.

I would however be interested in ADDING a front fender mounted driving lamp in the style of the GTV. I imagine a downscaled GTV housing blended into the fender curve, with a smaller LED cluster wired into the high beam circuit.

But vintage Vespas generally don't have batteries ...
If you want to mount LED lamps and not overload the electrical system you will have to install a battery and the current rectifier.

He wants to use this on a GTS, not a vintage Vespa.

I still don't know what bulbs, connections etc are in his proposed new lamp. Without knowing that, there's not much can be said about any connections to the scooter's electrics.

Jim .... do I understand correctly ...? Do you really mean that he intends transform in rat scooter a modern Vespa? I understood that he wanted to do it on a vintage Vespa. Ouch!
So I go to my wall where I usually hit my head when i'm confused.

Jimc:
Sorry, I didn't make myself very clear; what i would like to achieve is put a combined DRL/Indicator into a spot light housing - the innards of the existing spot light will be completely removed and discarded - the intention is to have something akin to the standard front turn signal units (the DRL and Turn Signal lights and associated wiring etc) but housed inside a spot light and with the DRL as either an Angel Eye ring or as a central bulb/led cluster.
Please ignore the photo above, it was only intended as an representation of what I wanted to use.

Attila:
I like to work on the mantra "my scooter, my money, my decision" and while you find the idea of 'ratting' a new scooter abhorrent, I have exactly the same feelings about people who stick lights, mirrors and all manner of Mod paraphernalia onto any scooter; but hey, its their money, scooter and choice so prefer to criticise them on a public forum. And, yes, I know I just did.

I don't find it a repulsive idea ... just a little strange.
But I understand the desire for distinction, but yes...there are so many ways to spend money and time and this isn't one of the worst.

aa-gts, Although you can combine the two type of light I don' think that is legal here in the Uk in a spotlight housing. It has to be an indicator housing for the indicator lights, purpose made meeting EU specs, and if you can get the daylight running light in it that's still ok. Although indicator housings can and do vary in size pretty sure using spotlight housings for indicators would not be legal above a certain size, although daylight running lights can vary in size by quite a bit if mounted separately. I'd research that a bit more. I'm ex tech and used to MOT vehicles and from memory it'd fail a test with what you propose and you'd likely get stopped by the fuzz too. Correct me anyone who has something different on this if it's changed recently!

So...Scooterwest sells a kit for Switchback DRL/Turnsignals in the existing turn signal housing. I've done this and it's worked flawlessly for 15K miles or more. And it wasn't difficult to install (I was able to do it), but I did put in uprated bulbs for greater visibility.

You could use that as the baseline for your electrical; mine plugged directly into the harness in the headset. You would need to mount a light bar I think (or maybe a modified front rack to simplify things), and you could run your wiring through the horn cast cover.

Bulb selection is going to depend on your preferences. The idea of angel eyes is interesting, but simple all in one switchback LEDs would keep things easier and deliver the desired effect.

Good luck and post pics of your project.

Cheers CrazyCarl, I'll take a look.

Do you want both DRL's to go out when signalling a turn, or just the side being used? Did you want the DRL to be the same color as the turn signal, or different?

If you are gutting the lights anyway, probably easier to have multiple LEDs in the housing, one set for DRL and one for turn indicator. Wire the 'turn' LEDs to the normal flasher circuit (although you may need a special LED flasher unit) and the DRL elements through a relay that shuts off when the flasher circuit is activated. You'll want to take that signal from the switch circuit, rather than the flasher, since I'm assuming you don't want the DRL elements to alternate with the 'turn' elements when the flasher is activated. If you don't want both DRLs to go out when signalling a turn, will need a relay for each side.

If you are into computers, might be fun to use a Pi or Arduino to run the lights, and program in some interesting patterns, as well as automatic turn signal cancellation.

If you'll settle for same-color, just power them through individual relays, and use the turn signal 'on' to turn the relay off. Again, may need to use a special LED flasher unit, or add a ballast resistor to the circuit to allow enough current to keep the flasher operative. Take the power from the headlight circuit, so the DRL's go on and off with the headlight. If using LED's the current should be sufficiently small as to not cause problems.
