Might give these a go, as like you say the standard ones are poor.
Found some on eBay for £9.95 + 95p p&p. it says the angle is 180degrees
Admittedly eBay is swamped with Cree 501 bulbs. Just be careful you don't get anything which is too wide or long. Problems will arise when it comes to fitting. The angle on these is probably not far off 180.
