    FOR SALE Plug and Play Headlight Relay Kits

    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...

    68 Charger headlight question

    I don't know the crackedback kit, but it is pretty straightforward. I ordered my relay kit at the same time I ordered new headlights. Unless the kit you are talking about is made specific to your car you will get a more stock look by making your own harness, like I did. I just cut the headlight...

    68 Charger headlight question

    You can buy H4 headlight relay harness off eBay for $45 bucks and Octane also sell good conversion kit. For me, I went way more complex and highend. It all started when I realized the headlight were only 9 volts going to the headlights. I found 12 volts at the bulk head and 12 volts at the...

    What did you do to your Mopar today?

    68 Charger headlight question

    I build my kits FOR our mopars. They are not a one size fits all. There are things you DO NOT want to do that many of the lower cost kits do not address. I have a database of lengths for placing relays under the battery tray for a hidden installation. Many that are particular are about...

    Headlight Upgrade?

    Halogen is probably the simplest upgrade (Hella brand should be close to a proper fit) but will require relays as they use more power than traditional incandescent bulbs. Im working on LED conversion now but this requires extensive cutting of the headlight buckets and at least on the 67 Coronet...

    Get brighter headlights

    Just a heads up on CrackedBacks vs. eBay. You’ll be much happier with Robs stuff than the copycat garbage on eBay that uses lesser products.

    68 Charger headlight question

    You have an excellent solution for folks that want to keep a stock look. You need to advertise more. Maybe list on eBay and Amazon? My solution was to deal with ground trigger coming from the Holley EFI ECU.

    Headlight Replcement Question On A 1970 Roadrunner

    The LED bulbs cost over $100 each and require a new headlamp housing like the ones Octane Lighting or other companies sell. However, theses usually require cutting either the headlight bucket or the radiator support or both due to the larger backend. Here's a picture for illustration purposes...

    Headlight Upgrade?

    I guess you just don't realize the difference between Xenon HID system and a quartz halogen system . The HID system produces 3x the LUMENS (the correct unit of light measurement) than Quartz-halogen lamp or bulb. A QH lamp consists of: Tungsten filament, a Quartz glass bulb and Halogen gas...

    Get brighter headlights

    I also agree a good first cheap step would be a headlight relay kit. Either the member here or ebay or make your own.

    Get brighter headlights

    Four bulb or two bulb. plug and play with ceramic bulb female plugs if you go halogen (hot) . It uses your existing headlight controls to work the relays. Super simple mod.. https://www.ebay.com/itm/Dodge-Headlight-Relay-Wiring-Harness-4-Head-Lamp-Systems-Fix-Dim-Lights-H4-/281203172816...

    Derwud's 70 Charger R/T build.

    Started working on the Wiring. I am REALLY liking this American Autowire Classic Update. Dash and rear are almost done. Need to wire the stereo/Amp and trunk lights (Car never had the option, but it is part of the kit, so I added it). Then engine and front lighting.. Having a Power probe and a...

    Help with ‘63 headlights.

    Best headlight upgrade in my opinion is installing a headlight relay kit. I did this a few years ago on my 63 Polara and what a difference. At the same time I also replaced all 4 headlights with stock halogen units. This also takes a big load off of your headlight switch.

    Who has experience with Hella H4 headlights?

    I use the KC H4's on my Nova track car. They're for a Jeep, but we made 'em work. Needed to get away from glass. The car has a Ron Francis harness and we used a Ron Francis relay kit for the bulbs. I know they have a "relay relief kit" for retro fitting the H4's like you are thinking. They have...

    Headlights are dim

    Easy way to prove voltage drop. Negative meter lead on lamp pin, positive meter lead to battery post. If you measure greater than 2 volts drop you have a connection issue and grounds are not an issue. Friends 1959 el Camino had 9v at headlight pin. He replaced everything and only a relay kit...
