Anyone replaced all tail bulbs with LED?
I'm about to get clear tails... i've replaced all my interior lighting, my license plate lighting, and my front/rear trunk lighting with LED and LOVE them... was thinking about going to all LED's in teh tail lights...
anyone done this yet? opinions? |
Current plug-in LED's simply do not work as well as the original incandescents at illuminating the reflector and lens. Though you'd be gaining the benefit of quicker illumination time and longer bulb life, you'd be losing quite a bit of overall light output, and sacrificing safety and visibility as a result.

Try the LED 3rd brake light! That's effective. |

http://www.ledtronics.com/ds/aut1157/ sells LED tail bulbs that output 100lumens in red... this link: http://findarticles.com/p/articles/mi_m3012/is_2_184/ai_113602893 On top of that a typical rear stop function an incandescent bulb needs to generate about 400 Lumens of energy to net 75 lumens of energy by the time it gets through the red lens. A red LED only needs to generate 75 lumens because you don't need the red lens. not saying anyone is wrong, just trying to get clarification... when someone says it won't perform as well/efficient... HOW much difference? 10%? 75%? |

The second link/article is talking about where the LED is directly exposed through the rear -aimed directly to the rear... like most factory LED taillights are. You can't really compare those to the LED-styled bulbs. Plus, your Boxster's lights have a lens. I've tried the LED route (not in my Boxster). In daylight with a chaser car behind me, they were unable to tell that I had my blinker on. At night time, it's easy to see the blinker, that is until you turn on your parking lights. Granted, every car's lighting set up is different, but the overall result is garbage, and NOT safe. That's the biggest issue I have with it. Not so much for blinkers, but definitely for brake lights. One other thing, you may have to install a regulator so the thing doesn't blink too fast. It's not hard, but you'll have to be comfortable with splicing wires on the Boxster. |
I tried inserting LED bulbs into the Boxster and they did not work, since then someone on this forum has successfully put LEDs in his Boxster tails but he had to do some rewiring of the LEDs
I bought a set of LED taillights assemblies. These appear to be OEM but have built in LED lights in the running lights and the brake lights. The blinkers and reverse lights are stock bulbs. These LED assemblies are very bright. They are much brighter than anything I have seen on the road. I wish there was a way to show everyone how bright these are. From my research on LED lights for our cars there are 2 full assemblies made the one I have that looks OEM and another one that to me looks like the Carrera GT lights. Ebay has them both for sale. The other lights are not as bright as mine....how do I know? I have a set of them also. So after this long post my opinion is if you want Bright LED lights and an OEM look get the LED assembly like mine. If you want LEDS as bright as stock and a different look. Get the other set. After I tried the LED bulbs in the Boxster I tried them in my X5 I can tell you that they looked better at night than OEM bulbs. I do not know how thay looked during the daytime, but at night the LED bulbs look great. I have rambled enough. |

These are the lights I have and recommend them http://cgi.ebay.com/ebaymotors/97-04-PORSCHE-BOXSTER-DEPO-RED-SMOKE-LED-TAIL-LIGHT-NEW_W0QQcmdZViewItemQQcategoryZ33716QQihZ023QQitem Z360025282509QQrdZ1QQsspagenameZWDVW This is the other set of LED lights, I like the fact it is a different light pattern than OEM but these are in my opinion only as bright as OEM http://cgi.ebay.com/ebaymotors/97-04-PORSCHE-BOXSTER-986-EURO-RED-CLEAR-LED-TAIL-LIGHT_W0QQcmdZViewItemQQcategoryZ33716QQihZ019QQit emZ290208571017QQrdZ1QQsspagenameZWDVW George, it sounds like you really know what you are talking about when it comes to lighting. All I am basing my opinions on is what I have seen with my cars. I agree a LED is unidirectional so perhaps these lights are designed in such a way that the light is aimed so they appear brighter. As far as which is brighter in a laboratory I don't know. Maybe after the lenses on the OEM lights the brightness of a standard bulb is reduced below what this LED setup I have puts out. I may try to get a video of the lights this weekend but I dont think it will translate well. |
This is a picture of the car with the lights on, If you look on my fence you can see the red reflecting off off my fence. Notice I have Christmas lights and my "garden" lights on. Also, my outside flood lights are on casting alot of light onto the car and fence. It is very bright in that area of may yard with just the floods on. For any red to show on the fence is an accomplishment.

This is a picture of the car taken in front of my office, you can see 2 of the 6 security lights that are lighting the parking lot. With this picture you can see how much light is reflected off of the ground. From looking at the LEDs there are none of them aimed at the ground.

Lat one...
Same night as the other picture. You can see how wide the reflection is on the ground. I am not a professional photographer, i guess you can see that. But I hope this give a good idea of what these LED lights are doing for my car. |
If you couldn't guess by now, LED replacements do NOT work in 986 tail lights. Another thing to add is that not only do the optics not match, but the bulbs are further angled in the housing. So, those Letronics bulbs will signal the guy in the adjacent lane you are stopping, but not the guy behind you.
If you want LED tail lights, there are plenty of LED tail light housingss available. Just don't use the bulbs. |
Gary those are some amazing pictures. I take back everything I said about LEDS :)

I put leds in my parking lights in the tail light assembly but had to take the bulb apart and reverse the wiring inside the bulb to make it work.
The OEM boxster tail light assembly put the all ground (negative) on the bottom of all the bulbs and power (positive) on to the side of the bulbs. Led bulbs are polarized and assembled with pos on base and neg on the side. So Led bulbs will not just plug in and work in our OEM boxster housing, with the exception of the wedge type Led bulbs, that you can just turn around. So our OEM boxster housing is the limiting factor in using LED bulbs in our tail lights. Thought about replacing the 3rd brake lights with wedge type of Leds next, requires 8 or 9 of them. These bulbs below are suppose to be close to filament bulb type, but are very pricey to me. But won't be a direct replacement for our OEM tail light housing. http://www.superbrightleds.com/specs/1156-xLX5.htm http://www.superbrightleds.com/specs/115x-xLX3.htm Another thing about those bulb with all the extra leds, it might be too big to fit in the holes of the housing without modifying it. Good luck, Jay |
