I noticed that when I put a new brake light switch in that if you get the wires the wrong way around the Srs light stays on have you had the wires off. As for the 3 light it ended up being the shuttle valve switch on the abs pump , put salvage part on and had it reset at garage £30 that was 2 week ago then all of a sudden when driving on a gravel track slowly it's back on again so going to reset
