I noticed this the other day, the dome lights are a little bit brighter when in the ON position rather than the automatic on when door is open position. Probably 5-10% difference.

B2 - who notices stupid things

 

Was the engine running during both situations. If not one was done when the alternator was supplying the current and the other when the battery alone was supplying the current. Might explain the difference.

JPP who somethimes notices stupid things also...but not that stupid

 

Oh yeah. This was with the car OFF.

 

Boring day at work?

 

Jet lag at home... I noticed this at 4AM in the morning.

 

Hyperwhite dome lights are the shizzle

 

PIAA Extreme White to be exact

 

its b/c in ON it gets straight 12v w/o have to go through a relay (the one that is tripped by the door)

 

Exactly.

 

dome light? this is what i think about that fuggin light...

 

That's why I swapped it out with another light that still doesn't do jack!

 

Package. Note: Price is in NT

PIAA v Stock

Light it up:

Xtreme...Almost...:

I replaced mine with a higer wattage bulb from the local auto parts place. stock is 4 watts, I think... put an 8 watt bulb in there and CAN notice a difference for like the buck or so it cost me.

 

I'm getting an HID kit for my dome light.

 

lol, Gordy!

 

BustaNutt, your explanation is very close, with the diff. there's not a relay involved. Like you said, when the domelight switch is in the "on" position, the circuit closes direct to 12V (there is less resistence). When it lights up by the door pins it goes through longer conductors creating more resistence. That's why the light is less brighter. It's just a simple "ground" circuit.

 

Nerds

 

 

dorks!! hehe....pretty good observation. wonder what you do with that light to notice it.

 

Let us know if the plastic cover melts. ( Just in case someone leaves their door open long enough )

 

where can i get some of those hyper white dome light bulbs yo?

 

i have 10,000,000,000,000,000 candle power bulbs to fit the dome light holder, only thing is they melt the roof when on and you'll go blind if you look at them!

 

The bulb is constantly supplied with 12V. When you turn the light on via the switch at the light you completing a ground through the switch. The door switch does the exact same thing, except that the ground is through a long piece of wire, which has resistance. Therefore some of the voltage is dropped across the wire due to the resistance of the wire. The ground path of the switch at the light is a short path to ground and will have much lower resistance than the long ground wire, so more voltage is dropped across the filament of the bulb, thus it will be brighter.

 

my god....$520 Nt = ~$20! (30 NT = 1 dollar)

 

bored much b2?
