<b>Subject: </b>[Healeys] Brake light switch</p>
</div>
<p class="MsoNormal"><o:p> </o:p></p>
<p class="MsoNormal"><span style="mso-fareast-language:EN-US">I recall several years ago that there was a discussion on the poor quality of Healey brake light switches. At that time several people advised that a Harley brake light switch worked and worked better
than the original. <o:p></o:p></span></p>
<p class="MsoNormal"><span style="mso-fareast-language:EN-US">I tried checking the archives but I don’t know how to check by subject rather date – if it can even be done. What I need to know is either the Harley part number or the years and model Harley that
the switches are from. Can anyone help.<o:p></o:p></span></p>
