LED lamps are very cool but very directional and do not illuminate the fluted plastic lenses on the VX very well amking the overall look a bit dimmer IMHO. 18W Malibu lamps are a great deal but do get a bit hotter - I have added them to my front and rear side indicators as flashers only and they are sooooo much brighter and hotter - I don’t know if I could leave them on as running lights without melting the plastic and certainly would not put them in the horn lights.
BTW; I will be offering a kit to add lamps to the front and/or rear side indicators. Very easy to install and very effective for safer lane changes. the bulbs point backwards towards traffic and really get people’s attention. Kits should be ready late next week.
