I tried yet another type of LED bulb in my XEvo today. For the last few months I've been running with one LED 501 wedge tower like this:

and one normal amber coloured W5W wedge bulb each side. I did this because I wasn't happy with the standard bulb's giving a non-descript and easily misable pink hue but also wasn't entirely happy with the LED towers because although much brighter and more obviously orange than the standard wedges, they were much more directional, and viewed from some angles just gave small pin pricks of light which again could be missed.
SO, I ordered a couple of these:

Which were described as Ultimate 1 Watt Ultra amber LED's which although just one diode gave a supposed wide angle 120 degree spread of light.
I only ordered two rather than the necessary four as I didn't know if they'd really be any better and they were £6.50 each bulb!!
However compared to the LED towers they do seem to be. They're certainly much brighter and definitely more orange than the standard wedge bulbs. Viewed from directly behind, the towers give a bigger reflection in the indicator reflectors, but the source of light from the ultra LED's is brighter. The difference between the two is more noticible when viewed from more acute angles, where the ultra LED gives a band of reflection off the reflectors when the tower's light disappears into pin pricks. See what you think from the following photos and video. Remember both of these types of bulbs give a more definite amber/orange colour than the standard bulbs.
Top is the tower, bottom is the 1watt ultra. Viewed from a few angles.



And a video.
