I don't think we have seen all the advances in led technology yet, I think they wilk continue to be improved, there was talk of a new ceramic material (I think) making them easier to make but I've not heard anything else on it

The cheap led bulbs on ebay make a huge difference to the interior lights in cars

I fitted a couple in mine, nice white light instead of a dull yellow glow.

there excellent and getting better by the year . just don't believe the crap they last 25 years. I've fitted hundreds. out of that about 25 have been returned faulty and they were branded names. I date every bulb I buy with a waterproof marker and the supplier

Don't you get any customers complaining about the big shadow writing on the wall?

The problem with individual LED's are the light angle which is determined by the reflector, then range from 8 degrees as a pin point light with a long range, to a wide angle LED of up to 180 degrees for an individual LED with a short range, to overcome range and spread it is prudent to mix wide and narrow angle to get the correct mix of LED's for a decent light output.
Where the various chips are used it is all determined by the number of mirrors and the angles, some manufacturers are doing single chips with multiple mirror angles.

I've fitted LED's to a couple of cars with mixed results, I did the dash on one car and it vastly improved the warning lights plus you don't get the problem where you miss a warning because the bulb has burnt out, but on the other hand I did the front sidelights on the wife's Pug and both of them blew inside a couple of months.

u will buy cheap crap
You cheeky sod, cheap crap my **** I spent all of £3 for a pair of them deliveredu will buy cheap crap
Ok so I've bought cheap once and been burned, where can I get some quality T10 wedge LEDs suitable for fitting as sidelights ?

dunno I only buy the 240v ones and there's hell to pay if wholesalers sell me a duff make and don't let on there crap and get loads backA common mistake people make with vehicles is the incorrect resistor value, they often base calculations on 12 volts and don't realise that the average car battery is around 12.6 volts, and when its charging the alternator can provide up to 14.6 volts (depending on make) into the lighting circuits.
All the LEDs I used were nominal "12 volt" versions suitable for use in a car so they should be able to cope with the normal range of voltages seen in a car.
If I was calculating my own resistor value to use with an LED I'd base it on a 15 volt supply just to be on the safe side, either that or use a voltage regulator or a dc to dc convertor to stabilize the supply first.

all the household 12 volt led bulbs use a led driver. that's a posh name for a 12 volt dc regulated supply as the3 bulbs don't like overvoltage and don't last as long

I've been using Auto Bulbs Direct for a few years, only had one (H7) failure and that was replaced FOC.
Link to the LED wedge bulbs, does the T10 have a No. equivalent?.
I've had good results with these... EBAY LINK
(I think T10 is the same as W5W?)
bought a few others to try on work vans and they didn't last long, those have been in for a few weeks now and no signs of failing - vans are out all day every day with lights on, so other bulbs only lasted a few days
those are brighter than stock bulbs, but not super bright... I think the led drivers in the super bright ones are what fails... I know the really bright ones ran pretty hot and failed the quickest
slight side note... put some of THESE in as reversing light bulbs and it's an awesome difference.. much much brighter... and I figure as reversing lights they won't be on much so should last a long time
picking up new forklift yesterday and I left van in reverse with ignition on to use them as light while we loaded new forklift onto trailer... loading didn't go to plan so they were on about 3 hours straight, didn't miss a beat, and I've ordered them for all the other vans now...

As long as they're designed for the vehicle voltage (nominally 12v or 24v) they will draw as much current as they need. Indicator bulbs are a special case as LEDs don't draw enough current to operate the flasher unit correctly so you have to provide a load in the form of a resistor. Some bulb failure circuits may give problems too.
