When I did mine I am sure it was only a few pounds, got them from e-bay and never had any problems, polarity issues were solved by inserting them the opposite way, I do understand why that wont work with bayonet fittings :)though I never had these issues, maybe a PF v FL thing?

Yea that works with the wedge and festoon .... but not the bayonet..

Found that out when I installed and they wouldn't work... contacted supplier
and was advised to just turn them around and wala .... we have light... :)

That was my point - whatever the fitment turn them around, but i got shouted down lol :p

Perfect...... Much appreciated +++

ECS is notoriously bad for shipping costs here in the States. I'd contact them about a group buy or about combining shipping for them. I have them in my car and output is excellent.

This is what my interior lights now look like; fronts first just awaiting small LED panels for the map lights (they're still mini-BC halogens).
Second picture is the rears and third is "in the beam" to show just how bright they are. (I'll try for a night-time pic later)
Fourth picture is "similar" to the front main bulb (42mm) and fifth is the rear bulbs - 2 each side.
I think that lot (5 bulbs) cost in total about £4 on eBay!

huge improvement - I like! +++

Thanks. :cool:
The colour is good, actually pure white, not at all blue. Look great at night. :love:

And you can tell they're bright from the daylight comparison - sun is sort of "trying" to break through thin cloud so it's a pretty bright sky.

And here's a couple of grainy non-flash pictures taken on my phone; gives you an idea, especially how nice it is with the lights on in the back:

Can anyone say specifically which screws and where; I did see something that said there were just 3 and they were "obvious" - not to me though... :o

No, just corrected. :D
(that only works for wedges, not bayonets)

PS My "spare filament bulb count" is now about 20 and still rising, just from fitting LED's. :ROFL:
