led light bulbs

I have always hated the dim, yellow interior bulbs.  So I started looking for bright white LED replacements.  One thing LED (sorry) to another, and I ended up buying new LED bulbs for everything except the headlights.

Autolumination.com is the most comprehensive automotive LED site on the Net.   Huge selection, good tech info, reasonable prices, and quick shipping.  What more can you want?

I'm happy with the results.  The crisp white light makes me smile every time the lights come on.  The "super white" light is a little too blue to me, but it beats the yellow of stock incandescent lights. 

The chart below shows the bulb numbers (autolumination substitute size in parens), the autolumination name (product numbers would be nice), and my comments.

"utility light" (white)

I am replacing the underhood light entirely.  One weak little bulb is not enough.

"SMT Tower 18 LED"

Nice looking package.  Not installed yet.

"forward 1 LED"

A little dim.  I'm going to try something else.

43mm festoon

"Festoon High Flux"

6 wide-angle LEDs.  Brighter and more diffuse than the "Superstars" used for the map lights.  May actually be a little too bright.

"Superstar" (2 1-watt LEDs)

2 "Super High-Flux" LEDs.  They work great.  You have to remove the overhead fixture to replace the map lights.

"Wide Angle Matrix"

Radial side-facing LEDs are needed because the bulb points to the rear.  This bulb is a good choice.  Just the right amount of light, aimed in the right direction.

"Superstar"

One 1-watt forward-facing LED.  Compact package fits well in the small bulb space.  Have not yet had a chance to install.

"Superstar w/heat sink"

3 1-watt forward-facing LEDs.  Heat sink to handle the output.  See photos below.

Spiderlite X2

Not available from autolumination.  Great lights, though.

 

All bulbs are "Super White" except for the front turn signals (amber) and the SpiderLite X2 taillights (red).

 

Installation notes:

 

LED lights are polarized.  You must check to see if they light up before reinstalling the fixture.

 

To replace the map lights, you have to remove the overhead fixture.  The silver reflectors are removed by pushing back on the end of the reflector that is highest.

 

To replace the ashtray/cupholder light, slide the ashtray full forward.  Then push it back in a bit.  To get it out, find the barbs holding it in and push down on them while pulling the tray forward.  The bulb socket twists out for bulb replacement.

For the license plate light on my Sir Mike's roll pan, I had to get creative.  Nothing would fit the housing, so I gutted the housing, disassembled one of the 2-LED festoons, and soldered and epoxied the guts of it into the housing.  Works great so far.
Although it's difficult to tell from the below photos, the Spiderlite X2s (left) are just a tad dimmer than the existing taillight bulbs ("Bermuda Black" taillights).  But the color is much better; the stock light looks orange in comparison.  Note that the X2s are "three times brighter" than the original Spiderlites, so I would definitely stay away from them.

The backup lights are also noticeably dimmer, but again the color is much more pleasing (the photo makes the stock reverse lights look whiter than they really are).

The brake lights are a pretty close call, but again the stockers (right) appear a bit brighter.  Nonetheless, the LEDs are much quicker and redder, so I suspect from a safety standpoint, it's probably a draw.
The blinkers will flash too quickly.  To combat this, dropping resistors or an electronic flasher is required.  The photo below shows the area where the flasher is.  It is behind the stuff shown in the photo.

Turn the turn signals on.  You have to remove a cover to get to it.  Reach underneath and you will feel the cover vibrating.  Remove the cover.  Underneath are two relays.  If you feel carefully, you can feel which one is for the turn signals.

The replacement relay that I used is Tridon/Stant EP27 electronic flasher, and then an off-brand Chinese electronic flasher.  Neither completely solved my flashing problems with all lighting combinations.  I ultimately added 3 Ohm equalizing resistors.  I spliced them into the rear turn signal/license plate light sub-harness, which can be removed so it can be easily done on the bench.  The turn signal wires are green w/orange stripe and blue w/white stripe.  Each should be tied to the ground, which is the thick black wire.
