I found the above sets inconvenient if not danger.
We had several good topics about nice sets, but they don't show in searches anymore.
Here is my final design where glow step makes nice landing leveled with bumper step and
HERE is topic how we brainstormed different designs. 
Bedlam has different idea about starting glow step above the bumper, what avoids single step over basement much higher than the rest. Than basement is no longer easy accessible.
I am thinking about adding step above the bumper to my setup. That would require additional support, like block of wood between bumper step and additional glow step.
That idea is on hold as additional step cost almost $100 and I have other project on my driveway.
