It is safe to replace the headlight H7 low beam regular bulb with a LED type?

LED "plug-n-play" bulbs will never be bright enough for main beams. you can replace the fog lights, since they are useless anyway.

Never say never :)

Would be for sure cool to try if someone has spare $50. Looks cool in the picture but if one had access to a light meter and would be able to test stock lights VS his VS this led at a distance.

+1 Technology chanes so fast. Someone try it out the kit and let us know :D
If not for my factory HID, I might give it a try...

I wouldn't say that. I've been experimenting with some of the COB (circuit on board) style LED's here at work for equipment and industrial lighting applications. I have an LED element the size of a pencil that puts out more light than the two 2x4 fluorescent light fixtures over my desk. Damn near blind you looking at it.


And with that said, those retrofits won't work. They might be bright enough but the beam pattern will probably be worse that an HID kit. An element that large will have light scattered everywhere. For reference the unit pictured below is 10 watt. I'm seriously doubting the units in the link above are 40 watt. More likely 6 watts (2 x 3 watts). They may be playing "numbers games" like they do with fluorescent bulbs. It may put out light equivalent to a 40 watt halogen or that is the actual amount of power they draw on the circuit, not bulb power.

notice i clarified my statement with "plug-n-play" LED bulbs. properly designed LED headlights can be as bright or brighter than stock halogens. but plug-n-play bulbs, especially those found on ebay, will not be worth it for replacement headlights.
 
3200K is on low side. I think the white halogen bulb is 4100K. my initial question was if a LED bulb can be use it as a substitution of the regular halogen bulb. I want a white light (4100K +) and I don't want to spent $60 for a pair (silvania ZXE) that will last 1yr (that is what i was told at advance ap). Now, the type of output or beam can be increased or decreased with reflectors and I think that the LED can be a good option for the ZXE. the problem is that I don't know if I have to buy a conversion kit or just plug-in's. The conversion kits that I saw on ebay, the bulb has fins and they will not fit in the housing. I am going to buy a regular plug-in to see how it work, they are not that expensive. I will let you know.
 
That looks interesting - if true, the lumens are definitely bright enough (3200). Of course this would be illegal to put in any car since the optics are not designed for it - probably lots of glare. Off road rally lights may be.
Wouldn't our projector lens refocus the beam unlike standard halogen lamps that rely on reflectors?

I did a quick google and COB LED lights seems to be the new wave. Folks are asking but not many have tired it. There is a Mz3 person who tired it and the issue was the cut-off was actually too low but not sure if the person readjusted their light. I have hopes this will work out but heat seems to be a problem...

Optics are optics, doesn't matter if reflector or projector. They are designed with the light source in a particular location and for a particular size. Halogen light source is not the same as HID is not the same as LED. The location and size of the light source are different relative to each type of bulb. See http://www.danielsternlighting.com/tech/bulbs/Hid/conversions/conversions.html for more information.

On the other hand - HID may be closer to a Halogen light source - which according to the reference above, is still not good enough, but these LED light sources appear to be a lot different than HID or Halogen.
 
thank you guys. LED's are the future and they look really cool. I read something in Car & Drivers about Mercedes Benz is working with LED's on their cars. Very soon the halogen lamps and HID will be replace them with LED's. This is happening already in the Building Construction Industry, were lighting fixtures (all types) are being replace by LED. By the way my next post will be why Mazda is refusing to install a temperature gauges in their cars. I believe that it is very important for a car guy to have a temp gauge in his car. Low cost cars do not have temp gauge. therefore why Mazda is refusing to install them? where is the Zoom Zoom?
 
i don't know why you thnk you need a temperature gauge, BMW's don't even come with an oil dip stick...

Go be the early adopter and let us know :D. Based on the little that I’ve read, I too get the feeling things are moving towards COB LEDs. Low profile, high output, low cost, lower power consumption, what’s not to like (excessive heat seems to be a concern)?

You mean coolant temp, right? If so, almost all cars are now moving towards dummy gauges. You should have a light that comes on when the engine is cold and goes away once you reach normal operating temp. Anyone have experience what comes up if you overheat?

How fitting it is a Mz5 gauge cluster in the article!.. Article says manufacturers find folks tend to follow a light more but I personally call that horse crap and believe it is cost cutting 101…

More often than not a stock temp. gauge is worthless anyway. By the time it starts creeping up and you notice it's too late and the damage could be done. If you absolutely must have one, then you can buy an aftermarket gauge to keep an eye on things.

If the 5 is like the 2nd gen 3 then a light will come on when the engine starts to overheat.

That's good to know and make the dummy gauge a tad more acceptable but still not preferable. Whether the temp gauge or tachometer (on autos) are worthless is highly subjective to the user.

Another question: I understand the engine cold light is a “cool” blue (makes sense). Is there another light hopefully in red or orange that comes on when it starts to overheat or is it the same blue light? I hope it is not the same cool blue light…
