Review: Great value and fit. Replaced OEM bulb with no insulation issues. Quality packaging and part. Would buy again.
Review: I believe in using original equipment replacements but the price difference is ridiculous. Took a chance after researching and was pleased that it installed (Google procedure) easily enough. POV: If the tube doesn’t fit the housing when replacing make sure there isn’t an o ring in the housing that you left in when removing the old tube. Do it, don’t waste your $.
