Brake Lights are too dim-alternatives??

  • Sponsors (?)


You need to overhaul the entire lense unit and housing for everything to look the best.

Use chrome spray paint on the inside of the housing. (You will have to remove the lense from the housing to do this.)

Here is a write up.

And use this as a guide to polishing the plastic lenses.

Polish the OEM lenses, and the brighter light from the chrome spray paint will make a difference. :nice:
 
why are they dim is what you need to figure out....do you have a weak ground??has the plastic taillight housing clouded inside or out if so clean them and polish with i use aluminum polish to remove haze on the outside takes some elbo grease remove and clean insides with a good cleaner and bottle or cup brush.....if not those do the other lights seem to be dimmer if so have the electrical system checked its free at most autoparts stores could be a battery,alternator or voltage regulator going bad.repost results and findings, and/or repost in tech for better results

maybe some brighter bulbs as well, brake light bulbs are 3157

do an ebay search for 3157 light, or 3157 LED

I found these http://cgi.ebay.com/ebaymotors/3157...tegoryZ33713QQihZ005QQitemZ150062073500QQrdZ1

instead of 1 bulb, its 20 LED lights, you can them in different colors, they should be tons brighter
just bought them. After I get done cleaning the lense and putting this led light in, the difference should be night and day.

2nd ebay purchase of the night:flag:

Sorry to piss in your cornflakes man, but those "white" LED lights aren't gonna work at all. :(

The red lense will filter most of the visible light out, and you will be left with nothing near "bright" :(

For an LED to shine as bright as possible, you need to match the LED color with the plastic lense color.

You really need RED LEDS for red lenses.

The white LEDS are going to be more dim than the stockers.

Here is some reference material regarding the RED leds and the visible spectrum.

Which Color LEDs should I use ?
For best results the LED color should be the same as the lens color. As an example: a red lens will filter out all but the red portion of the light so if the light is all red, none or very little light will be blocked by the lens. The light from a White LED contains very little light in the red portion of the visible spectrum so most of the light would be filtered out by a red lens.

forget the led bulbs...i went and tried some of the ones you can get almost anywhere and they just shine bright, but straight out the back, and were pretty much blocked by the long plastic strip on my Cobra lights. they dont reflect around the housing good at all
 
Well the style that face only out arent going to reflect off the housing very well at all.

Stick to this style LED bulb and you will have better luck.

The problem with those LED's is that even though they spread the light all over, the original bulb is still brighter.

I have first hand expeirence. I swapped the reverse lights and lisence plate bulbs on my GT to LED and test ran the bulbs in the taillights. They are the same 18-20 LED bulbs as above, but just not as bright as the original old-style bulb.

They look cool as hell though :)

They are white, but look purple in the pic.

(taillights are normal bulbs, i didn't take a pic with the LED's in, but they are a tad bit dimmer)
