Tachometers

  All Rocketman Tachs are converted to modern movements with state of the art circuitry. These are not repaired or rebuilt tachometers - the only original parts used are the dial, bracket, case and pointer.

So what does that mean?
  It means that you are getting a brand new tachometer with only one moving part, the same technology used everyday in automobiles, boats and aircraft world wide. It also means that your converted or new tachometer will plug directly into your MSD tach port with NO tach adapter! Best of all, your tachometer will bolt right in like the OEM unit and do all of this while still looking original when installed.
  It also means that you are no longer relying on 50+ year old technology that can leave you stranded. Anyone who has ever been stranded by a Ford inline tach can tell you it's not an experience they want to repeat. So why take the chance?
My tachometers are BRAND NEW inside, professionally built in the USA to my specifications and are about half the price of 50 year old technology repaired with used 50 year old parts or the homemade 3 wire conversions offered by other shops. My tach movements are so good that I offer THE ONLY LIFETIME WARRANTY in the business. In fact, that warranty applies to clock and ammeter conversions as well.
  * I have been told that some people will not work on the aftermarket Rally-Pacs or the Faria style Tachometers with plastic cases and stop pins at zero. Don't worry, these tachometers are no problem at RCCI.


All of my new products come with a lifetime repair or replace warranty. As long as you own it I will stand behind it.
Just send it back to me with a note telling me what the problem is and I will take care of it.
Used parts have a 1 year replacement warranty.
Orders within the state of Texas will have 6.25% state sales tax added to their order.

Prices are in USD. USPS shipping with insurance in the continental USA is only $15.00 for most items.
Additional shipping is charged for multiple items, oversized items, international and shipping outside of the US lower 48.

Volt Meters

  All Rocketman Volt Meters are converted to state of the art circuitry. These are not repaired or rebuilt meters - the only original parts used are the dial, case and pointer. Unless you request otherwise they are calibrated to read centered at 13VDC, so you can tell at a glance what your charging system is doing - to the right of center is charging, to the left of center indicates discharge.

  • Volt meter works with all 12 volt charging systems - original, 1 wire, internal regulator, external regulator, etc.
  • The pointer will NOT be centered like an Amp gauge without power. When unpowered the needle will sweep far left to show 0 volts.
  • Mustang Volt Meters come with a 'fluorescent red' pointer that looks like the pointer did when new.
  • Ammeter conversion and prices are for OEM ammeters only - NOT new aftermarket ammeters. I do not convert aftermarket meters.

  • All of my new products come with a lifetime repair or replace warranty. As long as you own it I will stand behind it.
    Just send it back to me with a note telling me what the problem is and I will take care of it.

    Headlight Relay Kits

      Converting your headlight wiring to a modern relay type is probably one of the best 'bang for the buck' mods you can do to your classic car. A must when using modern halogen bulbs, it will also brighten your original incandescent headlights.
    Normally this is done by cutting the main wiring harness and splicing in a pair of relays. Most of us try to hide the relays under or behind something as well. Not only is this a time consuming task, it can be troublesome if a connection or component fails and you have no lights!
    My relay kit can be installed in less than 1 hour without cutting your harness. Not only that, it can be easily removed for shows or if it should ever fail. The kit also has built-in redundancy** that virtually guarantees that you will never be in the dark.

    Check out the video done by OperationMustang.com: Doc reviews the RCCI Headlight kit

    All kits work with 2 or 4 headlight systems. Click here to see if an RCCI Headlight Relay Kit will work in your car.

  • Recommended bulbs: Direct replacement halogen bulbs are available from most car parts stores as #5001 (low beam - outer) and #5006 (high beam - inner) for 4 headlight systems and #6014 (be sure it says HALOGEN on the box) for two headlight systems.
  • **Full and International kits only. Read product descriptions for details.
