Decided the orange lens front indicators on Morton jarred too much with the red paintwork. Without doing too much homework ordered these on eBay for under £20 the set delivered.

Firstly no issues fitting supplied orange bulbs as the pins are in line. The L691 lens are shallower than original and are not supplied with a reflector as OE although they fitted ok. Not happy with the pin point orange glow though so decided to swap the reflectors over from original.
This is where the problems started. The new lens have ten internal braces molded in and each requires a semi-circular clearance in the chromed plastic reflector. Painstaking work with a Dremel and appropriate tool soon had those added though, and once the mount stands were cut down to match shallower lens all fitted OK.
The reflector adds a great improvement matching original glow well.
