All of my LED's are from Diodedynamics.

+1 for Diode Dynamics. Love my SL1 LED headlights.

1) Philips Vision LED installed in place of incandescent bulb: killed the side-marker functionality of the taillamp. So now people are less able to see your car from the side. Second, the LED lit up fine when I turned on all the lights. But, when I had someone hit the brakes, the entire LED bulb shut off. The back of the car went completely dark (save for the CHSML). Neat function! And this is a "5-star" LED with the package saying it's "road legal" and it's all backed by a 12-year warranty. For some reason, brake light bulbs that shut off when you hit the brakes make me think that you won't be around long enough to cash in on the 12-year warranty wink.

2) Sylvania LED installed in place of incandescent bulb: killed the side-marker functionality. The LEDs lit up fine with the lights on. But, when I had my helper hit the brakes, the brake light did not get any brighter, which is the expected/correct behavior for this car. So, again, people behind you don't realize that you've hit the brakes. The package says "lifetime warranty" but for some reason, I don't think that you'll have a particularly long lifetime with taillamps that don't work wink.

These are products sold by Sylvania and Philips. Who do you think is more likely to be sued for selling crappy products--Sylvania and Philips, or some random factory in China pumping out LEDs that are only sold on Amazon.com? What are we going to do, extradite some poor chap from China for causing people to get rear-ended? The reality is that few people give a crap about whether you live, die, or end up paralyzed for life--not even Sylvania or Philips seem to care smile.


I’ve found those Sylvania and Philips LED’s are VERY application specific. I had the Sylvania ones in my Durango and they worked but needed a resistor to make them not hyper flash (the ultimate reason I removed them). Filled the brake/turn light perfectly, dim mode was similar to the regular bulb and the turn/brake mode was a little brighter. But the dinky little 194’s for the tailgate lamps? Absolutely garbage.

I don’t recommend switching to LED if you have to wire in resistors... if you put a resistor in and the LED fails, the car might not know the LED has failed and you won’t know you don’t have any brake lights unless you check them frequently.

I like LED tailights, they turn on faster and thus might shave precious milliseconds off reaction times. OTOH less heat being made means possibly being coated in snow in bad weather. They certainly can be brighter and sharper.

I was thinking more along the lines of your chips, if you were working a for a semi that in turn supplied an OEM (or one of their vendors), then it's a 2 to 5 year wait. China, that's more like 6 months I'm guessing, consumer products are much faster out the door, and wild guess here on these bulbs is that it's not OEM quality level. wink



Interesting you mentioned the faster light up time....

Very true.

When I installed a led right tail light. . I noticed it came on faster than the old left side. I thought that was very peculiar. Well I got a led just yesterday for my left side .. now they both light up just has fast.

Don't you mean in series? In parallel would reduce the resistance/increase current. I've never used load resistors to wire in LED's so no first hand experience. It's been a long time since I've played with circuits...30 years?!

No, the proper way to wire them is in parallel. You're right that wiring the resistors in parallel would reduce the resistance and increase current. And that's exactly what you need to do to keep the bulb-check light from turning on. Think about it: if you have a burned-out incandescent bulb, how much resistance does it have? How much current is flowing through that circuit? The answers: infinite resistance and zero current. And that's what makes the bulb-check light turn on. An LED bulb has very HIGH resistance and draws a very LOW amount of current, just like a burned-out bulb. (low current = low power consumed = energy efficient) If you want the bulb check light to stay off, you need to decrease the amount of resistance and increase the amount of current in the circuit. The load resistors consume power (more power = more current flowing through the circuit) which keeps the bulb-check light off, but negates at least some (best case scenario) energy savings (negates ALL energy savings in worst case scenario).

I can see you've dealt with automotive qual in some capacity... ;^)
