speaking as someone who does not yet own a Volt most people would wonder why I would be putting this thread up. But its something I have been looking into doing with the Volt when I happen to stumble upon a Volt myself. So a know a lot of people are asking about why doesnt the Volt have more LEDs assorted throughout the Volt. Well like I have done on my previous cars I have upgraded almost all the lights on the car to either LEDs or HIDs. of course with the Volt it will not be as easy as the headlights on the Volt are HIR? correct me if I'm wrong. and there are only a few scetchy aftermarket HID manufacturers out there who make HIDs for 9012. But like I was saying LED install on the Volt I could imagine being a little difficult as being cladded in aerodynamic underside pannels and who would really want to mess with all that battery power with that? Well I'm sure someone will soon attempt to change the Lights on the Volt to LEDs in order to save precious elecricity. As everyone knows the back of the Volt is pretty much all LED as it is. I haev a list of Bulbs for those who dont know the list yet, from what I read from the downloaded manual I could only find 3 bulbs numbers. I have a list of bulb numbers and the locations.
High & Low beam headamps: 9012
Parking light/front turn signal: 7444NA
License plate/Map light: 2825
Dome light: 194
Step/Courtesy light: 7065
Trunk: 175
I got those numbers from sylvania.com I am a an advid user of V-leds.com I have put V-leds on my car and have not had one problem with any of their bulbs I also have their HIDs installed too. most of these bulbs then converting to LEDs can be used in more than one place:
2825=194 on V-leds on their website, you can get the others if you serch the web for leds to fit the other bulbs on the Volt, I will email V-leds with the list of bulbs they do not have and see if there is any way they could make special orders for the volt or somehow rig up their current bulbs to fit with these # bases so they could fit for everyones Volt to make power draw less. You can go on and order LEDs on the web from other vendors but I myself know the quality and brightness to vleds leds and I hope vleds will make this wish possible for us.
One more thing I have is for those who I know have been saying the reverse bulb for the Volt is quite dim (I stated in my other post that the reason for one single reverse bulb is the fact that the Volt is also the Opel Ampera and some European countries require only one light even if there are spots for two lights, only one can be functional.) long winded. But on V-leds web site is a license plate frame that when in reverse funtion lights up very bright. This will obviously aide in reverse visibility, make your others know your reversing and also greatly help out the reverse cam as I have hurd the reverse cam at night is merely useless.

that is for the reverse frame, the web adress for vleds is simple vleds(dot)com. love to hear input, trying to be usefull!
UPDATE!!!
I got an email back from the V-leds reasearch team and he gave me the following information
OK, from the top…
The 7444 can use a 7443
The 175 is indeed a 168
The 7065, is this a festoon style? Like so - (if so I would need to know the measurement tip to tip. Prefer metric)
The 9012 are a modified 9005, I will have to do more looking around!
You can do the switchbacks in a 7443 for sure!
Check out v-leds(dot)com and see what he is talking about with all the number parts.
For vleds website if you want to change the bulbs that are currently incandecent. on their website you can buy a 7443 LED and it WILL work in your Parking light/turn signal locations. what he meant by the switchbacks for them is a dual changing from white to amber multiple LEDs. what this means is, when you have your car on and the lower bumper parking lights on driving they will be a White color like your DRLs in the corner of your front headlight housings, just like those, so it makes your front parking lights look like fog lights, which during the night obviously will help out in visibility. The cool thing about them is, when you go to turn and put your blinkers on the white LEDs get turned of and the Amber ones turn on and flash amber just like a normal turn signal.
Like I said before 168 LED can fit into your 175 trunk bulb with whiter brighter output
and I did research and 7065 IS a festoon style that will fit into your step/courtesy lighting.
and the 2825 LED will fit into your map light and license plate bulb.
so far there is an LED to replace all your incandecent bulbs in your Volt to save those precious surges of electricity to light them up! With further research going into the headlights we should find a quality HID system to put in there, but as of now its practically the same as the 9005 but with a little different. If there are any questions dont be afraid to comment or PM me. I'm still gonna keep in touch with V-leds for further delevopment.
UPDATE!
I just got word that the 9005 and 9006 bulbs will fit in the 9012 sockets but with a little modification, the little tabs on the base just need to be trimmed. more info on the way.
