Diode Dynamics LED bulbs flickering
As stated in the title, has anyone had issues with the HP3 194 LED bulbs from diode dynamics? Got mine 6 months ago and 2 of them start flickering after 20 seconds of being on. Replacements have been sent thanks to their great customer service but I wanted to know how often it happens. Thanks!

I have the interior & exterior LED package from Diode Dynamics and i havent had a single issue with their bulbs or quality. Also, i had a few of their bulbs on my old car and no issues there either. You might have just gotten a bad bulb or something, but their customer service will take care of you

IMHO you're getting them replaced by DD so all is good. I've had my DRL LED's warrantied by them with no issues.

You can contact DD for warranty replacement. I've gone through 3 sets with the same problem. If you have these for your license plate lights, the problem is that the solder joints seem to be cracking with repeated temperature cycles, usually only in one of the three LEDs in the bulb. It's pretty easy to resolder them but you have to be careful about not reflowing the solder that holds the two boards together, just the LED.
I've started using Philips and it's been good so far. |

It's interesting you ask this. I have all DD bulbs in my entire car... and have for years... without any issues... APART from the HP3 bulbs. I had THREE of them go bad on me (the ones used in the front side marker housings, as well as one of the rear side marker bulbs.)
Here is the email I sent to Diode Dynamics. I was impatient and ordered HP5 bulbs to replace them before they even answered me (they're cheap anyway), so this was more of an FYI for them than anything else. They've always been helpful, and I love all of their products, and continue to buy from them (my most recent purchase was a $200 aux light kit for my girlfriend's STI for Christmas), but I do NOT like the design of the HP3 bulbs, and I probably wouldn't buy those specific bulbs again.

Thanks for the input guys! Very interesting. I'll probably keep running the HP3 until I get annoyed of it going out and go with the HP5.

FWIW, the HP5 bulbs I replaced them with have been fine for me, so if you decide to replace your HP3s, the HP5 is what I would suggest.

HP3's are crap from DD. After three warrantied sets they replaced them with HP5's that have been fantastic. Wonderful service the whole time from DD.

One of my HP3's are flickering, so I ordered some new HP3's (Diode Dynamics charge you for shipping from Canada if you want to RMA something, which is pretty lame when the shipping costs more than a replacement bulb ). I'm worried they're just going to start flickering again after a year...
Do you guys find the HP5 too bright for a license plate? It's hard to tell from pictures, but I vaguely remember driving by another Subaru with a blindly bright license plate and figured he was using HP5's. If anyone has a video comparison that would be cool, too. |

Reading this thread has helped so much!
I was beginning to lose my mind with my HP3 side markers starting to flicker weeks after putting a new pair in. I am on my third replacement pair and highly considering just replacing them with HP5's but spending $40 for side markers and plate leds is a little ridiculous. Am I ridiculous for thinking this? Since this is apparently a known issue it would be ideal for Diode Dynamics to handle it without having to replace our HP3's over and over. |

I just had DD replace 3 sets of HP3 and again they are flickering again. I sent an email to try and upgrade to HP5 for free since the replacements and shipping was costing them. We settled at them paying for 1 set of HP5, I buy the second set and they pay shipping. They have been shipped and now I wait. Amazing customer service! Time to use the HP3 for the trunk light and my other vehicles! |

got a set of HP3 amber for my sidemarkers april 2016. only just started to flicker. looking into replacements now. I know I could warranty them, but they made it nearly 2 years, and tbh I don't want the hassle of worrying about when they break again. I do have a set of HP5 Red in my taillights. time will tell if they develop any issues. had them for roughly a year so far.

Sorry to revive any old thread, but my DD HP3 on the license plate lights are flickering too... I can do warranty but if I am in canada I wonder if it is even worth it.
Anyone know other options for LED plate replacement lights? |
