 We plan to swap the standard bulbs on our van with LED's, as so many have advised. As usual I get lost in the jargon. The bulbs I've just taken out say, as far as I can tell on the rather wobbly stamp, HP21W12v(E2). Or maybe it's "IHP21W  " etc.

Obviously I want 12v bayonet replacement LED bulbs, but what I don't know is how many of the numbers & letters in the spec have to match, for them to fit, and work!

For example, I get offered "380 BAY15D 1157 WHITE 12 DOME LED DRL SIDELIGHT SIDE LIGHT BULBS SLD200101"  and also "R5W BA15S P21W 1156 9 LED Car Tail"  which also looks the right thing, but again, I don't know. They both fit "standard" car tail lights, but I know from my own car that bayonet fittings and size vary in sometimes annoying ways!

So any advice on how much of these figures on the side of mine need to match would be very welcome please.

As would comments on how many LED's are needed for a useful light one offers "12 Dome LED", one 9 LED, but I'm (can't resist this....) completely in the dark about how many will be either useful or merely a poor glow-worm.

There are lights costing £2.99 a pair, and also ten times that - difficult to know whether it's worth spending the extra, or just a case of being ripped off.

Thanks as ever for all the shared expertise here,

Richard

    Hi Richard

    We have just done the same in our van and have replaced all the SB bulbs for a led version, was told by an electrician the either SBC or BC as used on the continent stands for "Small Bayonet Connection " and if its 15 or 222 thats just the size fitting so we were told!

    We ended up going into halfords one day and there you are 15m SBC led bulbs they were not cheap £15.00 for 2 but must say fitted into spot down lighters a treat and really work well giving off a bright light than the old one's

    I hope this helps you to chose don't mean to sound condescending about fitment types!Also advice came with a warning don't buy off internet as you are only getting cheap one's which are likely to blow after traveling to site

    I used similar to these, they've been in every spotlight and the over the door one in our van for 2 years and work fine, a nice 'white' light, not the blue tinge that you get with some others and 99p each with 4 for the price of 3 - if you're still unsure just order 1 and see how you get on perhaps?
