Lots of questions on lights

Yay thank you now I just have to wire it all up.

Lots of questions on lights

So I got 2 15 inch neon sticks that I am going to be installing underneath my dash.

I have some questions not sure how many, but here it goes. I am wondering what gauge of wire do I have to have?

I bought 12 gauge ground and power cord, and I am going to be hooking it up directly to the battery through a rocker switch. I was wondering is that going to be ok?

Also I was wondering what is the size of the dome light in the 2003 corolla? I was wanting to swap it for a blue LED one.

And I should definately have an inline fuse from the neons to the car battery right? Can I get the inline fuse at autozone?

Wire is plenty good, Inline fuse holder near battery connection (yes, auto parts store, plastic fuse types are available)

Dome light is # 3175 31mm X 10mm

I got a glass 12 gauge that is a 30a, I think it will work fine. Right now I am trying to make a cover for the thing on the left of the steering wheel to hold the switches.

I am having a hard time

Is there a specific type of fuse I need to get? Or just any fuse?

Small current rating maybe 10-15 amps would do. (you may get by with less, the smaller you can get by with the better for safety)

get a fuse from radio shack...10-15...and 12gauge will work i used 14-16gauge and used paper clips to attach it to the battery.(ghetto but worked perfect)

At that fuse current your wire may go before the fuse !!! Those lamps can't draw a lot of current, I would get a smaller fuse and use it ( it will fit in your new holder) CW

I was going to buy the ones like I have for my amp.

It's like a little plastic case that holds a 2 prong fuse, and then the plasitc covers the top. The problem was, it didn't say what kind of fuses it holds.

So should I return it and then get what type of fuse?

It's not really the type (glass or plastic, either will work) you just need a lower current than 30 amps. Just take your 30 amp with you to match physical size and ask for a 10 amp and it will fit right in. CW

Well I now managed to break everything on my car.

I bought a little point thing to test 12v wiring. So I am not getting any power to my end, where my rocker switch is going to hook up the neon.

So I go and get the wire tester and to make sure the bulb isn't broken, I push it into my power cord going to my amp, it lights up. So I am like ok, this is before the fuse on the amp power cord. Then I check it after the fuse and it works fine.

So then I check it before the fuse on my power cord going to my rocker switch. It lights up, so I check it after the fuse with a 15 amp fuse in. It lights up, this is all in the engine bay next to the battery.

So then I go to where the rocker switch is and I try and test the power cord for the neons there....nothing happens. I try and fiddle with the cord running through the grommet into the driver seat. Now I check it again, nothing, so I check the amp power cord running through the same grommet....nothing.

I go back to the battery and check both cords, nothing. Doesn't light up. Now my headunit won't turn on. So I have no radio and I am not getting power from either of those cords.

Which is wierd, the car starts fine. Everything work, headlights turn on, but the amp/radio and the neon lights won't turn on.

I am getting frustrated.

check your fuses. i did that one time when i was installing my head unit. i shorted something out by mistake. so just check you fuses, and your should be cool.

Hope it helps
