Plug and Play headlight relay kits
« on: February 28, 2015 - 01:27:23 AM »
Headlight relay kits that are essentially plug and play. 

There is a substantial increase in voltage at the headlight, increasing light output performance. Light output degrades exponentially with voltage input reductions. These kits also take headlight amp loads off the fragile bulkhead connector, headlight switch and amp gauge. The only headlight load flowing through the bulkhead is a minimal current required to trigger relays.

The kit includes:
Bosch/Tyco relays (no 1$ chinese relays)
Ceramic headlamp sockets
Fuses/fuse holders
12ga wire from alt to relays
12 or 14 gauge power wire from relays to headlight wiring (no 16-18 gauge wire like factory, except 16ga to trigger relays)
All terminals for hook up to a std 1/4 alt stud and ground locations
Wiring would follow normal wiring harness paths and be covered with black shrink tube for most of the run lengths.
-------------------------------------------------------------------------
NO CUTTING OF YOUR CURRENT WIRING HARNESS REQUIRED!



Road lamp relay kit is not included in the standard 2 and 4 headlight kits.  There is an additional charge for a road lamp relay kit.

The kits I've built have relays mounted on the yoke (front or rear), under the battery tray and inner fender uprights.

Picture of the light output difference from a 71 Cuda.  Both pictures are on low beam setting, Left - before, Right - after installation.
 

Another benefit that most users see are an improvement in dash light and marker light/turn signal brightness.
 
Some other things to consider.
Unless you buy wire in bulk, you'll have about $40+ before tax in different colored wire packages from a local auto store.

All kits I build are tested prior to shipping.

Kits for a 2 headlight vehicles are $135 + shipping.

Most 4 headlight vehicles are $160 + shipping.

The assembled kits fit nicely in a USPS flat rate box, shipping in the US would be in the $10-15 range.  International shipping is available.  Kits have been shipped to Canada, Spain, Italy, Germany, Australia, New Zealand and a few other countries.  Most all shipping is done via US Postal Service unless other service is requested.

Kits with all products and wire required to build one yourself are $85 for a 2 headlight and $100 for a 4 headlight + shipping.

If you would like some other iteration of a kit, parts only, please PM me.

All items are shipped from Indio, CA

Thanks to all my customers, I appreciate your patronage!

FWIW, I bought one of these kits for my '69 Dart 'vert and '74 Cuda from crackedback on a different forum. They work perfectly and are easy to install. Well worth the investment.

Very cool.   Don't need this quite yet, but I'm putting on my shopping list!

Did you get tracking info?  Says it should arrive on the 2nd.

Thanks again for the purchase.  Need anything else or any questions, please ask.

Im assuming this would cause the amp gauge to read incorrectly after installation?  Need to do something on my 72, lighting is horrible and gets REALLY dim at idle, including the dash lights

The amp gauge will continue to read the flow across it as it normally would.  Will it see the headlight load, nope.  The headlight load also isn't taxing the system any longer, execpt the minimal relay trigger load.

The kit removes the headlight load before the gauge.  The voltage regulator will still adjust what the car needs because the load requirements are picked up downstream from the removed loads.

OK, so the gauge would read low with the headlight load removed? Or normal? Sorry if they're dumb questions, electrical is not my strength

At idle it would read closer to normal since the light draw is not pulling down the amp load through the gauge.

Since I ran a #8 wire from the Alternator to the starter relay I added one of these LED plug-in Volt meters from Ebay.
With everything on and cruising down the road it stays right around 15 Volts...
Thinking I might change the power wire to the lighter to a switched source so I can just leave it plugged in all the time.
For now I just plug it in when I take the car out for a drive. It's nice to see the voltage and it was less than $5 bucks.
Plug-N-Play too!  :smilielol: Even I could install it! :bigsmile:

I got the tracking info, will finally be home tomorrow, and we will have our first 65+ degree nice day to boot!

                      That plug in volt meter is pretty cool. Since its LED you can just leave it in all the time, probably look pretty cool at night.   :2thumbs:

Those plug in voltmeters are a neat little item.  Remember an amp gauges basically shows you the directional flow of current. 

The fuseblock/interior power basically branches off the black wire from the alternator, prior to the ammeter.  Any reading on the ammeter should not change by pulling headlight power from your alternator charge stud, it's already pulled prior to the ammeter in your oem harness. 

Is there a buyers feedback area on this site?  If so, I'd like to leave feedback for all the buyers. 
If not, thanks to those that have purchased kits!   :cheers:

I'm a sucker for that kinda stuff so I just ordered one of the voltmeters. Hope it comes with install instructions, I'm not real good on electric stuff   :clueless:      :roflsmiley: :smilielol: :drunk:
