Folks,
A couple of weeks ago, I started looking for some LED headlights. There are a lot on eBay - some with different lenses, some with very funky lenses, and some that are just bulbs. I have Hella H4s in my -6 and wanted to stay with a stock look yet upgrade my headlights to the same Kelvin color range as the Euro LED turn signal package I got from Spoke a while back (very nice, BTW). I wanted the white of the headlights to match the running lights in the bottom of the front markers. A color of about 6000K was what I was looking for. After some research and reading some on the board here, I contacted VintagecarLEDs.com and told Thomas what I was looking for. Since I had the H4s with the glass lenses (and I really wanted to stay with them), he suggested that I look at his VC4000s and that if those sounded like what I wanted, he could sell me just the bulbs. Sounded good so I ordered a set. They shipped quickly and I got them installed before my trip up to the Okteenerfest. They went in easy (not any more than changing an H4 bulb besides the mounting of the small black box with the electronics) and plugged into the stock headlight wiring so no "difficult to undo" mod required. Additionally, the bulbs have an adjustable ring that changes the orientation of the bulb in the housing so when I was installing mine, I looked carefully at the stock H4 bulb and noted the orientation of the bulb element to the three -prong mounting ring that goes into the back of the housing. I then loosened the tiny allen set screw and adjusted the LED bulb to a similar "1 o'clock" position and installed them. The resulting beam had the same pattern as with the original bulbs - no need to even adjust the headlights. ![]() Wow, what a difference. I agree with others on the board here. They work great and really improve night vision as well as lessening the load on the electrical system. I had several guys at Okteenerfest ask me about them so I contacted Thomas and he graciously agreed to offer 10% discount to all 914World member who order from 9/30/16 - 10/14/16. If you want to take advantage, just go to https://vintagecarleds.com/ and when you're checking out, use the code "914WORLD" (all caps). Here are some pics. Attached image(s) ![]() ![]() |

The issue with H4s is not necessarily related to this bulb. The US/DOT requirement is that the H4 beam aim must not change when a bulb is replaced. The beam can easily change if a low quality replacement bulb is installed, because in a poorly made bulb, the filament is often improperly positioned. Of course the LED issue just makes that beam change issue potentially more complex. But most of these issues can be addressed by proper bulbs and adjustment of the head lamp.
A bit of a silly requirement if the beam aim can be addressed by proper adjustment. |

Our replacement VC4000 bulbs (if you check the photos on the website) the CSP LED's are laid out inside the bulb at the same focal point as the old H4 Halogen filaments. (exactly why the base is adjustable because regular H4 bulbs have a slight tilt to them.) I could take some comparison photos tonight of our VC4000 LED compared to a H4 Halogen for yall. It's pretty spot on. |

I could take some comparison photos tonight of our VC4000 LED compared to a H4 Halogen for yall. It's pretty spot on. BS. The halogen filament is at 0 on the focal axis. The LEDs are offset by 1/8" to the side. The filament outputs 360 degrees, LEDs about 270. There is no hard line answer for a good beam pattern, but LED bulbs in Halogen reflectors changes the engineered pattern and that is important to all drivers on the road. Post pics and include the brand of housing used. |

Post pics and include the brand of housing used. A halogen filament is not at 0 on the focal axis. I will post photos tonight showing how they are slightly offset. Yes, Filament is at 360 degrees except for the low beam which has a metal shield below it in a halogen bulb (will post photos, or look at yours.) Yes the leds are not 100% 360 as you have to have a heatsink in the middle. However they still work fantastic in a good quality H4 lens. Thanks- Thomas |
