Under Hood Lighting
 

We all know what a POS the under hood utility lights are when it comes to power consumption. Good way to kill the battery. Most put switches on them (as I have).

The current draw is 1 amp per light so that's 2 amps total.
Well I think I've found a way to drop the current to 250 mA per light.
That's 1/2 amp total for both.
Along with this comes 3x more light.
The answer is LEDs of course, that cure all for illumination of the modern age.

There are a few issues yet to work out but what I have clicks right into the stock bulb holder. No modifications needed.
Stay tuned. I'll post details as soon as I work out a few things.
In the pic below the left side is the stock incandescent light and on the right is the LED "plug and play" replacement.

Re: Under Hood Lighting
 

Love those leds I have them in my interior in cool bright white. Just completed the footwells

Re: Under Hood Lighting
 

Watching this with interest

Re: Under Hood Lighting
 

You and me both!!!!

Re: Under Hood Lighting
 

Hey GC do you have a list of the bulbs for the interior? It is on my list but seats are first

Re: Under Hood Lighting
 

Should also be a lot less heat on the lenses too and yes please post part #'s and where to buy...jimmy

Re: Under Hood Lighting
 

X3!

Mine are not working at all right now (bulbs are ok).

Re: Under Hood Lighting
 

Scott,

Nice...I'm in.

and GC...a second to Jeff's request for the list of interior LEDs. :handshak:

Thanks,
Paul

Re: Under Hood Lighting
 

Nice, Scott. BIG thumbs up!

Re: Under Hood Lighting
 

Nope I picked em up from Corvette HID. Yosi has the complete kit. He does not list the sizes either for obvious reasons. I will tell you coupled with Andrews Mirror upgrade that had the same LEDs it is one hell of an improvement.

Cylons are all about LEDs dont ya know :) I went with Cool White. Still need to get one for the Console. DA link is provided below gents. I will try to get a night shot to show you the difference as well. The kit includes the Foot Wells, the under the Mirror Map light (Which I did not need due to Andrews Mirror), the Halo panels and the Door handles.

Re: Under Hood Lighting
 

GC,

Thanks for the follow-up and refresh as to supplier.

Paul

Re: Under Hood Lighting
 

Paul if enough are interested I can ask him for a forum group buy pricing. I did order about $1400 of HIDS and LEDs from him. Im sure I could get the forum a better price. LMK GC

Re: Under Hood Lighting
 

I would be very interested in pricing. The interior lighting especially with the others for consideration. :handshak:

Thanks,
Paul

Re: Under Hood Lighting
 

I'm in .. anyone doing the tail lights? or blinkers ?

Re: Under Hood Lighting
 

You probably know this but on my 91 there is one inline 10 amp I think it is, spade lug two legged fuse just down below the left headlight area when the clamshell is up. In my case I like the lights and LEDs would be great but when you have the hood up for a while I've just chosen to remove the fuse, put the two sides of the inline fuse together and store the fuse. Easier than putting a switch in for me as I'm at the stage where I don't open and close the hood each time I do something around the engine.

Re: Under Hood Lighting
 

I'd be interested in their HID driving lights and maybe interior lights. Also the underhood lights

Re: Under Hood Lighting
 

Look at my seperate post up

Re: Under Hood Lighting
 

Nice job Scott, I'm in on both underhood and interior. Thanks for posting and Thanks GC for the GB set up

Re: Under Hood Lighting
 

Here is an update on the Underhood Engine Lamps (That's what the FSM calls them)
I thought I could get the power down from 24 watts (12W x 2) to 6watts. Well I've gotten it down to 1.2 watts and still so bright you can't look into it. That is 5% of the power and more light.

I've done an over night test leaving them on all night. Battery is still fine. The LED assemblies draw 50ma each.
I'm doing the write-up now. There is no cutting or butchering up of any wires. This thing plugs right in.

Re: Under Hood Lighting
 

Scott did you hand make these?

Re: Under Hood Lighting
 

You guys are killing me, Count me in for three sets of under hood and 3 sets Interior.

Re: Under Hood Lighting
 

Robert follow my thread and get your 20% from corvettehid.com

Re: Under Hood Lighting
 

Yeah Scott if it is a DIY project I am all for it

Re: Under Hood Lighting
 

I am going to supply the parts for a few $ to make it worth it.
Requires some level of soldering ability and eye hand coordination.

I may do a short run build but it'd have to be well worth my
time to do so.

I designed and assembled them yes. All parts are easy to get if you know where to look :)
I suppose I could keep private any development work I do on the car, but why?. I'll make it all open including schematics and circuit simulations.

Lots of time went into this including a build of several prototypes.
One design worked well but was not efficient enough. The current one is not only efficient but more light with fewer parts :blahblah:

For anyone the enjoys this sort of thing here is a plot of V across the LEDs and power dissipated by the dropping resistor as a function of battery voltage to make sure everything is kosher.

Re: Under Hood Lighting
 

I will buy a kit .. sign me up

Re: Under Hood Lighting
 

I'm in !!!

Re: Under Hood Lighting
 

Ditto...as long as you'll mail to Hawaii! I'd get two underhood sets.
Bill

Re: Under Hood Lighting
 

I'm interested also.

Re: Under Hood Lighting
 

Scott,

For those of us (me especially) that are electronically challenged :dontknow:, and do not have any testing equipment, what would a completed kit go for?

I know I could do the soldering, but I have no way of checking "kosherness". :???:

Thanks,
Paul

Re: Under Hood Lighting
 

I am interested in under hood, I do have a switch now that turns them on/off
Will that still work?

Re: Under Hood Lighting
 

Yes Phil since this is a direct bulb replacement. Cant wait to get my hands on a pair of these.

Re: Under Hood Lighting
 

Sign me up for a pair. I would need to have these built as I suspect most of the membership will.

Re: Under Hood Lighting
 

Ok I'm doing a poll to see how much trouble I'm getting into.
This poll is for 7 days ONLY. Anything after that may or may not get serviced since this is not a business for me. I design things. That's the fun part :p Cranking things out is drudgery.

Re: Under Hood Lighting
 

First in your poll Scott do you take Paypal? GC

Re: Under Hood Lighting
 

I noticed my underhood lights don't turn on, are they supposed to come on when you lift up the hood?

I wonder now if I have a switch , or if they are just burnt out.

If they are burnt out, is that common since our cars are pretty old now?

If there is a switch ... where is the common place to install it (where should I look?)

Thanks ---

Re: Under Hood Lighting
 

Yes, paypal will be fine but not quite yet. Based on the numbers I have to see if I need to hire someone to make these for me :icon_scra
Then I'll post pay options.

The assembly is not really trivial :-x

Re: Under Hood Lighting
 

I'd check to see if someone unplugged the connector. It's located just to the right of the passenger side headlight. Follow the wire down to it.
Next check the inline fuse. Maybe it was removed.
Then look for any switch that may have been installed. Most are put in the cove under the drivers headlight.
Lastly you can inspect to see if the bulbs were just taken out or are popped. The mercury switched would be last.
You can tap on them to see if they've become intermittent.

Re: Under Hood Lighting
 

YES

Both are possible and the switch is aftermarket. Its also more likely the previous owner unplugged the lights or pulled the fuse


Not common one maybe out but not both my money is they are unplugged or switched. Start following the harness.

It could be anywhere however mine is on the drivers side next to front of the tire in the engine compartment.

Re: Under Hood Lighting
 

Thanks Scott and GC ... if I can get these working I may be interested in the GP too :) ---
