Sorry you had a unsatifactory result. I didn't. I went from no lights WHAT-SO-EVER on the Speedo and Fuel and Temp, to lights that, although maybe not quite as good as the OEM, were at least visible! That is a huge deal! On a bright day, you can't see the needles AT ALL due to the contrast and at night the needles were invisible, so it solved the problem.
The "sham" I fell for was the problem was corrected for about $200.
This is really a safety issue that you would think, Toyota would have corrected. Bad engineering, really.
