Maybe its just me, but in comparison to incandescent and/or halogen and/or time wasting energy savers, the heat emitted from LED's is almost negligible?
Not that they dont ever emit heat, its just its so very little in comparison.

Yes, LEDs produce much less heat per lumen then incandescence. The problem is, as TLW pointed out, while incandescence thrive on heat, LEDs die on the heat. It's imperative to have some means of getting the heat away from the LED emitter and dissipated.

The thing with Bulbs, european law states you must carry spares. Since the phrech jondarm pulled a few drivers over for bad bulbs, which requires you to replace on the spot, then book you for not carrying a full set of spares being you just used them, its now SOP to carry TWO sets, so you have at least one full set at all times. Taking the bulbs out is a thing that when you drop a trailer, when you go to the next one, at least you know the bulbs are good, because they are your bulbs?. Rent-a-trailer when its not your own trailer your tugging, those places never ever rent you the one with the good bulbs, so, its common to take your own with you, as well as the spares, just to make sure you have a working set. The licence plate, if you swap trailers, drop one in one place and pick up another elsewhere, your licence plate has to be on the back of every trailer you pull, so you must take it with you?. here, if you are rented a trailer, you have the expectation that it will be in good working order before you accept responsibility for it if it is not in good working order, you demand that it be repaired or replaced and remind them that they have promised you a trailer you can use. and if the trailer is of the classification that it requires a license plate, it is assigned a plate, and the plate must be with it any time it is on a public road. if you drop a trailer in one place and pick up another elsewhere, the another had damned well better have its license plate. so I guess the difference is that: here, you are given reasonable time to get a bulb fixed or replaced, if you are caught with a bad bulb, the officer can either give you a warning to get it fixed (in which case if you don't, the next officer will see that you've already been warned) or give you a "fix it ticket" which you can take with proof of repair to court and the ticket will be cancelled. here, while the driver is responsible for confirming the equipment is in working order, the lessor is responsible for giving the equipment to the driver in working order. here, the license belongs to the trailer and may not be transferred from trailer to trailer. |

LEDs are unhappy above 80 degrees (f) www.lrc.rpi.edu/programs/nlpip/lightinganswers/led/heat.asp |

not one of them looks like it fits in my car, its not a twist lock, its a lever lock, and the "plug" is two pin push on and all held in place by rubber bung/cover inside the headlight hidey-hole.[waterproof covering that the cover/bung clips over...] Heat sink?. the LED's I am running, even the one in the kitchen in the house, they run cold to the touch?. why the need for a heatsink on an LED?. Plus the metal part of the headlight is a big enough heatsink for my halogen ones anyway. Maybe I need to go to the shop again, its been several months, I bet they do have LED that fit older Toyota's by now. I would suggest start by talking to your local autoparts store. Can they order in the bulbs for you? If you have one in your area, a shop that specializes in "performance" modification of cars is likely to have good sources for the right aftermarket bulb replacement. A final suggestion is to look online for aftermarket bulbs for your make and model. I have used Carid.com with good luck. I'm not sure what is available it the UK. |

Not that they dont ever emit heat, its just its so very little in comparison. Correct. When designing an LED lamp, you should design the heat sink for assuming 50% losses, then you are on the safe side even in summer. Monochromatic LEDs (red, green, orange, yellow, blue) are much more efficient than "white" LEDs and also they last a lot longer. A monochromatic LED is rated for many hundred-thousand hours while white LEDs are rated for a few ten-thousand hours. But this is only half the truth! Monochromatic LEDs are rated for when they reach 74% of their original brightness. For the logarithmic human eye this is about half the apparent brightness. White LEDs are rated for 50% of their original brightness which is an apparent brightness of less than a quarter! The efficiency of an LED is affected by temperature. The hotter an LED is in operation, the less efficient it is. An LED which is already running hot produces even more heat. First of all, less energy is radiated away as light so more energy turns into heat. ALso a hot diode conducts better so it draws more power in the first place so it creates even more heat. So when buying an LED torch, choose one which is heavy so there is a decent heat sink inside. |

In Austria you can also license a plate to several vehicles. This is great for owning classic cars so you don't need to pay extra for vehicles you rarely use. Since a driver can only steer one vehicle at the same time, you just pay tax and insurance for one vehicle. In Germany, this can't work. There are license and safety stickers on the plates. Those stickers mark the vehicle as registered, insured and "safe" (TÜV, a more strict version of MOT). |

[quote author=" c64" timestamp="1528025204" and then the car is permanently licensed. Doesn't work over here. We pay annual tax (and a fee) for the license. Then there is the mandatory insurance. Without insurance or paid tax/fees, you have to return the plates to have the sticker removed. And then there's the 2-year safety inspection which has it's own sticker. |

In the late 1970s (or early 1980s) there was a car which came with a large hole inside the glovebox if you didn't bought the A/C. You had to visit a garage to have your stuff retrieved... |

(for example, if you take a 1920 REO truck and put a 2000 drivetrain in it, you also have to upgrade the safety equipment to 2000 standards) |

I don't know if it is anything testable, but it occurred to me today when a Prion pulled onto the road in front of me to wonder what effect hybrid cas and hypermiling have on AVERAGE fuel economy, and if there is a proportion of hybrids to conventional drivetrains that marks the point where adding hybrids (with hybrid driving habits) goes between improving overall average fuel efficiency and hurting it.
(given that we have already established that conventional drivetrains have a different efficiency curve from electric drivetrains, and conventional engines are less efficient under less load.)

For the most part, I would think that in general, any high mileage car or driving habit would help to increase overall efficency. However, it does get complicated when you look at different types of vehicles. Hybrid SUVs don't typically get that good of mileage. A gas Honda Civic gets 32/42 city/highway per EPA testing. a Hybrid Toyota Highlander gets 30/28. So in that case, a gas car gets better mileage than a Hybrid, but it is not an apples to apples compassion.

So in that case, a gas car gets better mileage than a Hybrid, but it is not an apples to apples compassion. it is very complex math. but to greatly simplify it, if my truck is running under load, it burns approximately 5 gallons of fuel per hour, regardless of road speed. an electric drive vehicle has its energy use much more closely connected to road speed. so if I'm behind a prion that is going slow to conserve energy, I am burning fuel just as fast but doing it for a longer time. - and if it forces me to go so slow I have to downshift, then it is even more significant. |
