Functional with modification

It seems there is a lack of quality control where these bulbs are manufactured. 9 out of the pack of 10 had what appeared to be large globs of solder at the top of the base. Compared side by side with an old Osram bulb, I also noticed that the top of the base is flared slightly on the CEC bulb, whereas the Osram base is not. This flare combined with the lump of solder kept the bulb from seating properly in my HVAC control knob without being modified first. Depending on your fitment, you may want to consider a different option. However, if you do decide to go with these, the nice thing is that they're sold in a pack of 10, so if you mess one up, you have replacements.
