The seller has since said that for this car they recc this bulb?

first of all its white not red, secondly i cant figure how it can be dual wattage [21w and 5w].. ... - .- -.

Totally confused Stan. Have sent the seller that extract you helpfully offered from the manual. Response pending. Thanks

Stan, just getting back to the 50watt Cree bulbs.

You are indeed correct in what you say about the Cree leds current. Where it gets confusing is that this is each individual Cree led. So lets take the 400ma current. If we use the wattage formula then we can multiply 12volts times 0.4 amps or 400mA which equates to 4.8watts.

The problem with the 50 watt Cree bulbs you have is that it contains 10 of these Cree leds. Each one will consume a maximum of 400ma so if you times that by 10 it means the bulb has the potential to consume 4.0 amps or 4000mA. While the wiring will be fine with this my concern is more about the strain on the rest of the electronics to drive the indicators and whether or not this could cause long term damage I do not know.

If we take the standard 21watt bulb this consumes a maximum of 1.75amps or 1750mA. It might be that the electronics cope with the higher current draw of the 50watt Cree 4.0 amps no problem, but I would not like to say, and I certainly do not know enough about the overhead capability of the RR indicator circuitry etc.

ahh man, i thought i won that fight....

those calculations are a bit over my head Prop and i bow to your knowledge on this subject..
my mind goes to the red brake light that must be a fair wattage due to the brightness and i surmise your honour that if that can take the amps then surely the cree bulbs should be ok?...and because the indicators arnt used in a constant manor like tail/headlights etc then the wiring [if indeed put under a strain] wont suffer ... ... - .- -.

Stan, just wanted to keep you informed so you know the correct specs and can better calculate your risks, I am confident using just 2 of these bulbs at the rear should be ok. But running front and rear 50watt would be much more risky. And with all the conflicting info supplied its better to know for sure, I learn't a long time ago to take any specs given with eBay stuff with a pinch of salt.

The tail light bulb you mention is to my calculations about 6.5watts total power consumption as each 5050smd led is approx 0.24watts and when multiplied by the amount of leds, 27 equals 6.48watts. The 5050 led uses only a fraction of the power of a Cree led but is also no were near as bright. So even using 27 5050 leds I doubt that you will see the quoted 486 lumens output.

The 5630SMD led is a much better brighter led than the 5050 so I would recommend looking for bulbs that utilize multiple 5630 leds rather than 5050leds.

i only suggested the rear brake lights as a comparison because of their brightness but how do you know they are 5050's?

i think the whole indicator circuit/wiring is pretty robust because, as said before, you can charge the battery via the side indicator wiring but i wouldnt put any crees in the front..the main reason putting them in the rears was to have a brighter more defined light against the bright brake light.. ... - .- -.

i dont think anyone has replaced the OE bulbs with leds so this will be interesting ..dont forget the pics and your opinion on these Ryan.  ... - .- -.

I experienced initial minor problems fitting and/or removing aftermarket LED cornering bulbs and rear tail/ fog bulbs which caused some bulbs to break. This was in part due to the dry joints that can prevail when inserting aftermarket LED bulbs, partly it was due to bayonet pin position (on the rear tail/fog bulbs) and in part it was due to my fitting technique... gently does it... and I'm satisfied that these bulbs are of good quality and fit for purpose. Fortunately, the supplier of both bulbs is reputable and very customer focused, promptly supplying replacement bulbs FOC and without quibble.

Cornering bulbs - These bulbs have a two piece plastic housing that is glued together and due to the dry joints, on inserting the bulbs, hand pressure can cause the smaller of the housing pieces to break off. The bulb will still work regardless and you can compensate/ strengthen pieces by applying insulating tape before fitting. I was supplied with a replacement bulb and fitted it with no issues. These bulbs look very good on the car and they compliment the OE xenon headlights and the aftermarket LED sidelight bulbs I have fitted. They do not appear to throw out as much light as the OE cornering bulbs; however, they do work and make the car appear more visible from distance. They look right on the car and are not too bright *********************

The lower of the bayonet pins on these Tail/Fog LED bulbs need to be filed down in order that the bulb will fit the L322 bulb housing within in the rear light unit. Otherwise you will need to use so much force to insert the bulb and to remove the bulb that it will break the bulb. CTC and Stan of the forum suggested the pin filing method and it takes seconds to do, the bulbs thereafter fitting and removing perfectly well and without compromise to performance. The below links comprehensively cover my own and Stan's experiences of researching and fitting LED rear/ tail fog lamp bulbs which, a number of forum members first queried the need for/ feasibility of. However, the results achieved (pictured below) now seem well received by a number of forum members and from my own perspective, is one of the most pleasing, easy and cost effective upgrades that results in crisp, OE modern, improved rear visibility on the L322:
