    Default Is There Hope for Proper LED Retrofits in Headlamps ?

    Read this today, in a DVN report about the activities of the SAE Lighting Group.

    ...A new [SAE] task force is working on devising technical provisions for LED retrofit light sources (i.e., "LED bulbs" designed to replace halogen bulbs in headlamps). No such task force was ever convened for "HID retrofits", which are basically technically impossible to do in a safe and effective manner. But there is enough R&D momentum toward genuinely functional LED retrofits, and there are enough bogus products flooding the market, that such a task force is warranted.

    Cool! People have been waiting for something like this for a long time.

    Will be great if they can do it.

    If only the standards had been defined and the laws updated before the flood of bogus products came out.

    This is a great step, but it still doesn't spell the end of the crap being sold in stores near you. However, it should at least ensure that out of all those toys there ARE actual legitimate products out there. Remember, there are standards for replaceable light sources such as the HB4 and HB3 and H7, but that didn't stop (or prevent) the existence of the IPF Fatboy and other toy bulb-shaped products.

    SAE is also addressing the issue of headlamp lens degradation.

    The [SAE] Headlamp Lens Durability task force is coodinating tests with different lens materials (polycarbonate, acrylic) with and without annealing, and different coatings, to get a handle on ways to bring headlamp lens durability more in line with the long service life of modern cars and LED headlamps.

    This is one thing that greatly concerns me.... when the plastic lenses cannot outlast a light bulb and costs 20x the price of a bulb someone didn't really give it much thought in engineering and manufacturing design unless they considered the profit from selling new headlights every 5-10 years on cars into their margins. Someone needs to start a business selling covers for headlamps to protect them from damage that are cheaply replaceable so instead of having to pay hundreds of dollars for new headlights you can spend $20 for a new cover every so often.

    No, they put the thought into engineering and manufacturing a lens that satisfied the rather lax standards of the law.

    They sell those covers, but they need to be removed every time you drive because even the very clearest ones seriously degrade headlamp performance.
    And actual replaceable lenses designed by the factory would require so much effort in resealing the lamp and all that, that it wouldn't be worth it.

    The topic is LED retrofits, not headlamp lens degradation. Let's all (even the OP) stay on that topic.

    There have been posts/links to what seem to be genuine Philips LED headlight replacement bulbs, not the fog light versions that are noted as available on the Philips USA site. Is there a reason there is such a delay to the US? I'd be eager to get one, as opposed to the ones which are available from less well respected brands....

    Yes...please read those threads, where the reasons for what you call a "delay" are discussed in great detail. A (very) few of the best of the name-brand (Philips/Osram) LED retrofit bulbs work acceptably -- not well, not great, but acceptably -- in some headlamps. They are definitely not a drop-in that works (or even fits) in all/any headlamps that take whatever kind of bulb they purport to replace. And they're illegal no matter how well they work.

    Thank you for reminding me Virgil. You have jogged my memory, which seems to be getting poorer and poorer as I get older. Makes perfect sense.

    Still a work in progress: http://standards.sae.org/wip/j3145/

    Forward Lighting LED Substitute Light Sources for Halogen Light Sources

    ...The technology of high power LED packages has progressed to a level where applications involving LED Substitute Light Sources as Equivalents for corresponding RID filament light sources is becoming technically feasible. The SAE document is intended to describe the industry best practice in specifying such replaceable LED light sources...
    What does the acronym "RID" stand for?

    "Road" "Illumination" "Devices". Headlamps, fog lamps, and that kind of thing.
