Turns out I was wrong, there is actually a slightly amber bulb in the corner lights.. but I mean.. they are really not very noticeable. The only thing you will notice is the always-on amber light but that can be disabled with coding. Otherwise, basically invisible. The most immediately noticeable problem is the amber reflectors. Those MUST go ASAP.
