24volt HID's into 97 F350 any ideas

[randall3394]

I have a 97 7.3L and I have recently been given 2 sets of military 24volt HID's and am looking to mount them into the grill but I dont think my electrical system will allow it. I need some advice. Here are the voltage specs on the HID's there from Ibis Tek

2.94A@28.8volts

how can I make them work

Option 1: buy a step up converter to setup up 12v to 24v. 10a output should have enough overhead to make it work.

Option 2: install a second 24v alternator and battery bank.

Option 3: install a 24v generator in the bed of your truck and turn it on whenever you want lights.

why would u need t voltage transformer. our trucks have two 12v batteries. get a relay that can handle like 10ampd DC@ 24vDC and has a coil that takes 12v to signal it. come off the batteries wired in series to feeed the relay and take our existing feed to our headlights anf feed the signal end of the relay. not hard at all. and while you there install a relay to run our existing lights to get better preformance out of them and save the junk headlight switch from burning up

i hate how digikey dont give you pics on some stuff. font know it this relay is a sealed unit to keep under the hood but it just shows they do exist

I wonder what would happen when you take some batteries that are wired in parallel(12v) and then put them is series(24V) at the same time. That would most likely cause some sparks and smoke somewhere. That is not the same as a series-parallel circuit. You are going to need a dedicated 24V source (another set of batteries/alternator, or transformer)

Just spend some cash and just get some 12V HID lights. I honestly dont know much about pre 99 fords (sorry). Do your headlights use a sealed beam or a seperate small bulb(halogen?)?

i belive they actually take the same bulb -9007 on m 97- but nothing will happen to the batteries as they come pre wired like this stock. everything on our trucks is wired for 12v but they have a 24v starter. just ned to tap off of this line and hookem up.

Take a closer look at your truck's system. The batteries are in parallel and everything including the starter is 12v. Trying to connect the batteries in series at the same time they are in parallel will short the system, you would essentially be tying all the positive and negative posts together.

i stand corrected, i never really looked just thought..... i know some older diesels are 24v and never even looked at mine

my headlights came with 12v HID's 6000k, work great, and all 92-97 f-series and bronco's are 9007 bulb design, im pretty sure 99 and up are as well atleast to 04 i know of. but they are relatively inexpensive especially off ebay to get a kit for your truck to work em, how did you get military lights anyway?

I want to see a picture of these lights. I have a military truck with a full 24v system, some hids would be sweet...
