My car does not come with the engine bay lights that pop on when you open the hood, thus, making it hard to see in there at night. My goal is to add some bright LEDs to illuminate it. I tried the search function and found nothing so forgive me if this has already been covered.

Can anyone suggest a certain brand/type of LED for this project (white)? What is normally used to switch them on automatically when the hood is opened? In what order would I wire this up?

most cars and trucks use a mercury switch in the light housing too switch the light on and off.   it works from the level of the hood. 

you can use the same style switch and some lighting of your choice. 

like the leds you mentioned might not be bright enough if you just use one, but there is always that option of using more, more,more. and get it all at your local parts store. let us know if you need more help in specific area.

A single lumileds LXHL-LW3C will make a very bright engine bay light. Brighter than any factory installed light.

Hmmm... I was contemplating putting 4 leds hidden in the bay. Maybe something cheaper and not so bright? I'm undecided whether or not I want one bright one mounted like most or the 4 light option.

Put some LEDs together in a cluster  and attach them to the underside of the hood and voila, under-hood light.

Or you could use an LED dome light, either just the bulb or the whole thing (just make sure there's no plastic on hot stuff action)

A few more questions if you dont mind...

What guage wire should I use?
What is the usual way to tap a wire for power?
Are there any sites you guys can suggest that would carry everything I need with decent prices?

Thanks

i think something around 14 gauge would be ok for wire. and just go straight from battery to switch to led for power.

for prices.. alot of places, google led sales.

www.eled.com ?

The brightest LEDs readily available (5 watt Gen 3 Luxeon Stars) use less than 1/2 amp each. You could realistically use 20 guage speaker wire for them.

yup, leds you almost no power, so you can go with small wire, but don't go too small cause the wire might break with motion

Very true. That is why I went with speaker wire as it is usually a stranded variety. If it was in a firmer enviroment I would have went with telephone cable / cat3

Hmmm I can't seem to find anyone selling 5w Luxeon Stars except on ebay...and they arent white. There has to be somewhere that sells everything I need all in one site. LED, wire, heatshrink tubing, a 12v switch, and terminals.

The problem with Luxeon is that they gave exclusive distributorship to Future Electornics. All other sources of distribution buy from from Future. A 3 watt should be bright enough. BTW, Future dropped there price 40% on all luxeon products.

Also, luxeons will need to be mounted to heat sinks or a piece of sheet metal.

I would think that you should be more worried about engine heat then the LED heat, when it comes to the underlining.
