Cashed out quite a bit of ETFs in IRA- now a good time to shift more to bonds? (50s and very light on bond allocation)

As title suggests, I am mid 50s and very light on bonds. Couple of weeks ago I cashed out of a bit of ETFs (handwriting on wall) so cash heavy in that IRA. Is now a good a time as any to buy some bonds or allocate to bond funds with that cash? Or is there some 2nd shoe related to bonds I should hold a bit for?
